Only load the most recent messages when initially rendering a
conversation. Scrolling to the top of a message list loads older
messages.
This required some slight refactoring of how we insert message elements
into the dom. If the message is added to the end of the collection,
append it at the end. Otherwise, assume it is an older message and
prepend it.
When adding elements to the top, reset the scrollPosition to its
previous distance from scrollHeight. This keeps the current set of
elements fixed in the viewport.

Create a cleaner seperation between generating notifications
and updating frontend conversation views. The former is now
handled by `conversation.notify` while the latter is achieved
by triggering an event on the conversation model, which will
only be acted on if there are any views listening for it.
Additionally, instead of re-fetching the entire message history,
which is overkill, just add or update the new/modified message.
This will help speed up the newmessage event handler and also
help avoid unnecessary re-rendering when resolving key conflicts.

Follow up to ddd2e67eb5
but for incoming messages.
* Conflict state sometimes failed to be removed even though the
conflict was resolved.
* Messages failed to re-render after a conflict. We want to
re-render only the error state on outgoing messages, to avoid
flickering attachments. On incoming messages, we need to call
render to populate the message text, avatar, etc...
// FREEBIE
Previously, with a mix of text and media messages in conflict,
asynchronous callbacks aligned so as to fail to remove some of
the conflict objects on messages.
Fix by serializing conflict processing, but making sure to move
on through the message list even if some conflict resolutions fail.

For non text messages (ex: media messages and group updates), the
lastMessage field was being populated with empty string, resulting in an
empty message preview in the conversation list. Instead, display 'Media
message' or 'Updated the group', etc...
// FREEBIE
An exception to the previous commit, for incoming messages we should not
show a mysterious empty bubble. Instead there is some generic
non-technical error message.
// FREEBIE
Change how message errors are rendered. Errors associated with a number
will be shown under that number in the detail view rather than piling up
in the message bubble.
// FREEBIE
Fix inconsistency in error format, where we sometimes get an unexpected
Error object and sometimes get a wrapper object containing an Error.
Also start saving network errors.
// FREEBIE
Refactor outgoing message error handling to use the same success and
error handlers. This creates a somewhat strange pattern, where we call
send and pass in the promise that resolves when sending is complete, but
there's enough variety in the libtextsecure syntax for different message
sending routines that it belongs at the conversation level and only the
post-processing stuff is really shared by all messages.
// FREEBIE
The conversation's contactCollection only contains references to the
current membership, and will not provide contact info for people who
have left the group, causing their messages to render without numbers or
avatars.
// FREEBIE
Only allow one notification at a time. Use a basic notification for
normal messages, and image notification for image messages, and a list
notification when there are multiple unread messages.
// FREEBIE
This trigger function uses chrome's runtime message passing api, which
traverses between different windows in our runtime, but we only trigger
the updateInbox event from the backgroud page, so we don't need to use
that api, which requires some extra cpu/memory overhead.

This bug was caused by a race between indexeddb requests and sending
messages. Order of events to repro was roughly:
1. send async idb request for current message list
2. add new message(s)
3. idb request returns with now incomplete message list
4. message collection gets reset to list from 3, removing messages
added in 2, but not removing their phantom views/dom elements. (bug)
5. send another idb request for current message list
6. idb request returns bearing all messages including those from 2.
7. messages from 2 are added and rendered a second time.
The fix was simply to not remove messages in 4, which means we reuse the
original message model object rather than recreating it in 7.
Fixes#243

Update protobuf definitions and refactor message receive and decrypt
codepath to support new protocol, including various flavors of sync
messages (sent messages, contacts, and groups).
Also cleans up background.js and lets libtextsecure internalize
textsecure.processDecrypted and ensure that it is called before handing
DataMessages off to the application.
The Envelope structure now has a generic content field and a
legacyMessage field for backwards compatibility. We'll send outgoing
messages as legacy messages, and sync messages as "content" while
continuing to support both legacy and non-legacy messages on the receive
side until old clients have a chance to transition.
In a multi device world, it's possible to receive a receipt for a sync
message before the sync message actually arrives. In this case we need
to keep the receipt around and the process it when the message shows up.
Clicking on a key conflict message opens the message detail view,
which displays the contact(s) in this conversation. If the message
contains a key conflict with any of these contacts, a button is
displayed which attempts to resolve that conflict and any other
conflicts in the conversation that are related to that contact.
We'd like to live in a world where we can retry all the pending
conflicts in a conversation as a batch, which means we don't want to
wipe the identity key before processing each message. Thus, remove that
step from these handlers and encapsulate in a method on the conversation
model.
Sometimes a conversation's messages would be reverse-ordered on first
load, correcting themselves after a refresh. This is an artifact of the
order we load messages from the database. To fix, load them in the
opposite order.
The alternative solution would be to reset the collection every time we
fetch new messages, but this would create an entirely new set of model
objects each time, which seems unnecessary.
The message view has three flavors so far, a normal text+attachments
message, a group update, and an end session message. This changeset
extracts the normal message rendering into its own subview, and adds
some convenience functions to the message model in order to simplify
some of that flavoring logic.
This change removes the timestamp field from messages and conversations
in favor of multiple semantically named timestamp fields: sent_at,
received_at on messages; active_at on conversations. This requires/lets
us rethink and improve our indexing scheme thusly:
The inbox index on conversations will order entries by the
conversation.active_at property, which should only appear on
conversations destined for the inbox.
The receipt index will use the message.sent_at property, for effecient
lookup of outgoing messages by timestamp, for use in processing delivery
receipts.
The group index on conversation.members is multi-entry, meaning that
looking up any phone number in this index will efficiently yield all
groups the number belongs to.
The conversation index lets us scan messages in a single conversation,
in the order they were received (or the reverse order). It is a compound
index on [conversationId, received_at].
Move base64 encoding of attachments to an AttachmentView. This makes
image rendering an asynchronous task so we fire an update event to
indicate to the parent MessageListView that its content has changed
height and it is time to scroll down.
Getting up and running with IndexedDB was pretty easy, thanks to
backbone. The tricky part was making reads and writes asynchronous.
In that process I did some refactoring on Whisper.Threads, which
has been renamed Conversations for consistency with the view names.
This change also adds the unlimitedStorage permission.
Eliminates the global Whisper.Messages object and consolidates shared
send/receive logic in Whisper.Threads.
To the latter end, note that the decrypted array buffer on an attachment
pointer is now named data instead of decrypted, in order to match the
format of outgoing attachments presented by
FileReader.readAsArrayBuffers and let us use the same handler to base64
encode them.
Each conversation views now manages its own separate elements
rather than all binding to a shared #conversation element, and
similarly for message composition ui.
Also includes the beginnings of group creation UI (not working yet),
featuring bootstrap-tagsinput field for entering group recipients
When a thread is 'destroyed' from the UI we delete its messages and mark
the thread as inactive, (in other words, keep it around as contact info).
Additionally, we only load active threads when initializing the UI, and
reactivate threads when new messages are added to them.

There were a few problems.
1. The message event was being triggered in background, not popup
2. The initial message/thread fetches from localStorage were mis-ordered
3. The timestamp wasn't being extracted from the right place
4. #3 caused messages to fail validation and not be saved
1-3 are fixed. To address 4 I switched validate() to log a warning
instead of preventing save.
Adds thread model/collection for managing conversation-level state, such
as unreadCounts, group membership, thread order, etc... plus various UI
improvements enabled by thread model, including an improved compose
flow, and thread-destroy button.
Adds Whisper.notify for presenting messages to the user in an orderly
fashion. Currently using a growl-style fade in/out effect.
Also some housekeeping:
Cut up views into separate files.
Partial fix for formatTimestamp.
Tweaked buttons and other styles.
The 'sender' field actually holds the recipient for outgoing
messages. Rename that field to 'person', indicating the 2nd
party generically.
Also decouples the thread name from thread recipients at the
view layer, in preparation for group support.
Adds Backbone-based Whisper.Messages model/collection with local storage
extension. Saves sent and received messages in Whisper.Messages instead
of message map. This will assign a unique id to the message and save it
to localStorage.
Adds Backbone-based view to popup.html
Automatically updates itself when new messages are saved to
Whisper.Messages db from the background page.
Added some shiny new styles, and started splitting up css into multiple
files for sanity's sake.
