It can be moved if you're not scrolled to the bottom of of the window
or the window doesn't have focus when a new message comes in. Other than
that, it marches up the window until you close and reopen the
conversation, or send a message.
Note that we do NOT mark messages as read if they come in when you are
scrolled up. But we do mark the entire conversation as read if you
switch away from the app and back.

Re-renders happen when we re-fetch messages from the database, and our
previous technique for loading attachments resulted in a new attachment
view added for every call to render()
This change ensures that a second call to render() does not add any more
attachment views.

* Remove increment behavior
* Dismiss when new messages arrive but the window is focused
* Update the indicator when window becomes focused.

This is to ensure that when there are a lot of unread messages, the user
is given the chance to see all of them by being scrolled to the oldest
new message.
When a new message comes in, the indicator will be incremented.
When the user sends a message or switches away from the conversation,
the last seen indicator will be removed.

This was supposed to solve the problem of losing group state after a reinstall
by inspecting member registration ids and pre-emptively sending group updates to
those who appear newly re-registered, but it has been unused since 6123c419.
Nowadays there's a protocol for requesting lost group state from other members.

Add names and sizes for all attachments except images, and (as with
arbitrary attachments), clicking on the text will open a save dialog.
In the absence of a filename, choose something that makes sense.
Display different icons for different media types, including distinct icons
for voice notes and audio files.
In iOS theme, audio, video, voice, and files are all encapsulated in bubbles.

Check for early read receipts for an incoming messages *after*
processing the expireTimer on that message. Then we can set
expirationStartTime appropriately if an early receipt is found.

Bind a single listener to keychange events from the storage interface,
which then looks up relevant conversations and adds notices to them,
with tests.
Previously we would need to instantiate a conversation model in order to
start listening to its key change events. In practice this usually
happens at startup but we shouldn't rely on it, and it incurs higher
overhead since it creates a different listener for each conversation.
