ReplayableErrors make it easy for the frontend to handle identity key
errors by wrapping the necessary steps into one convenient little
replay() callback function.
The frontend remains agnostic to what those steps are. It just calls
replay() once the user has acknowledged the key change.
The protocol layer is responsible for registering the callbacks needed
by the IncomingIdentityKeyError and OutgoingIdentityKeyError.
This commit provides the javascript complement to
[WebSocket-Resources](https://github.com/WhisperSystems/WebSocket-Resources),
allowing us to use a bi-directional request-response framework over
websockets.
See websocket-resources.js and websocket-resources_test.js
for usage details.
Along the way I also factored the websocket keepalive and reconnect
logic into its own file/wrapper object.
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.
Register the runtime callback at the top level view rather than having
each conversation view register independently.
Also refactors Layout into InboxView.
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.
This dependency may be a little heavy for our current use case, but we can
roll with it for now and find something slimmer if it turns out yagni.

We only depend on cryptojs for this webcrypto polyfill, so let Grunt
concatenate them into one file.
The reference in the getString helper isn't needed since we use the
built in string converters on CryptoJS's word arrays.
Build with `grunt compile && grunt concat:curve25519` after installing
emscripten.
Enable by either (a) not loading nativeclient.js or (b) setting
`textsecure.NATIVE_CLIENT = false` before loading nativeclient.js.

Distills crypto.js down to the hard cryptoey bones. It pulls from
webcrypto for aes and hmac, and from native client for curve25519 stuff
or potentially another object implementing the handful of needed
curve25519 functions.
Everything else formerly known as crypto, including session storage and
management, axolotl, etc.. is now protocol.js. The separation is not
quite perfect, but it's a big step.
nativeclient.js now enables talking to the native client module through
a high level interface as well as registering callbacks that will be
executed once the module is loaded. And it has tests!
Finally, this commit removes all references to the "testing_only"
object, preferring to run tests on textsecure.crypto instead.
To components. Because tab-completion works better when there aren't two
things starting with bower, and shorter names are nicer to deal with in
general.
Set up grunt with tasks for:
* preen - deletes unused files from bower_components, configured in
bower.json
* concat - concatenates preened bower components, configured
automagically from the preen config
It's worth noting that this setup assumes the order of files within a
package doesn't matter. This is usually true since we often include only
one file from the package.
DRY up protobuf declarations and move to a slightly briefer naming
convention.
Also dropped some ArrayBuffer -> string conversions as
ProtoBuf.js handles ArrayBuffers just fine, and in fact, more
efficiently than strings.
Finally, dropped the btoa() wrappers, because that incurs an extra
string -> string conversion before the protobuf's internal string ->
array buffer conversion. In lieu of btoa, we can simply pass in the
optional string encoding argument to the protobuf's decode method,
which in these cases should be 'binary'.
