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.
* key API changes moxie made because he disliked the other API
* remove atmosphere
* Fix some bugs in the send path, update for new send API
* Send HTML
When included after api.js, fake_api.js inits a FakeWhisperAPI.
FakeWhisperAPI inherits the methods of API, overrides a few, and
then usurps its place as the one true API.
Single device mode successfully "registers" against FakeAPI. Sadly,
multidevice mode has a recursive loop somewhere that makes the callstack
asplode.
The details of the server API are now mostly relegated to api.js, and
accessed through the API container object, improving modularity and
readability, and setting us up to derive a FakeAPI for serverless
development.
