1) There is no longer a concept of "verified" or "unverified."
Only "what we saw last time" and "different from last time."
2) Let's eliminate "verify session," since we're all about
identity keys now.
3) Mark manually processed key exchanges as processed.
1) We now delay MMS notifications until a payload is received,
or there's an error downloading the payload. This makes
group messages more consistent.
2) All "text" parts of an MMS are combined into a second text
record, which is stored in the MMS row directly rather than
as a distinct part. This allows for immediate text loading,
which means there's no chance a ConversationItem will resize.
To do this, we need to include MMS in the big DB migration
that's already staged for this application update. It's also
an "application-level" migration, because we need the MasterSecret
to do it.
3) On conversation display, all image-based parts now have their
thumbnails loaded asynchronously. This allows for smooth-scrolling.
The thumbnails are also scaled more accurately.
1) We now try to hand out cursors at a minimum. There has always been
a fairly clean insertion layer that handles encrypting message bodies,
but the process of decrypting message bodies has always been less than
ideal. Here we introduce a "Reader" interface that will decrypt message
bodies when appropriate and return objects that encapsulate record state.
No more MessageDisplayHelper. The MmsSmsDatabase interface is also more
sane.
2) We finally rid ourselves of the technical debt associated with TextSecure's
initial usage of the default SMS DB. In that world, we weren't able to use
anything other than the default "Inbox, Outbox, Sent" types to describe a
message, and had to overload the message content itself with a set of
local "prefixes" to describe what it was (encrypted, asymetric encrypted,
remote encrypted, a key exchange, procssed key exchange), and so on.
This includes a major schema update that transforms the "type" field into
a bitmask that describes everything that used to be encoded in a prefix,
and prefixes have been completely eliminated from the system.
No more Prefix.java
3) Refactoring of the MultipartMessageHandler code. It's less of a mess, and
hopefully more clear as to what's going on.
The next step is to remove what we can from SmsTransportDetails and genericize
that interface for a GCM equivalent.

This fix involves setting transcriptMode to normal on conversation view,
which resolves the issue but comes with the side effect that if you
have scrolled away from the bottom of the list, new incoming messages
will not trigger auto-scroll as they arrive.
1) Update the create, prompt, and change passphrase activities.
They are no longer dialog themed, and should look a little
less ugly.
2) Update the import DB activity to be less ugly and more robust.
3) Abstract all of the state handling stuff out of
ConversationListActivity. This is now handled by RoutingActivity,
which all launch intents move through.
1) When sending an SMS or MMS to multiple recipients, only show one
ConversationItem, but provide statistics on the number of recipients
delivered to.
2) Still break up the messages for secure and insecure messages.
On platforms (API >= 11) that support receiving click events within
a notification, we change the notification format so that users
can "lock" TextSecure with a click.
For all platforms, we change the notification icon in the status
bar from a "lock" to an "unlock," to better reflect the situation.
This is all part of the master plan for eliminating the passphrase
timeout option.
1) Fix up the whitespace tagging so that it's a little more strict.
2) Don't display whitespace tags that we add to our own messages.
3) Make the tag detection prompt a little more visually pleasing.
1) Change all instances which use concatenation to build strings
with variables in them to use string formatting instead.
2) Extract all string literals from layouts and menus into strings.xml
3) Extract all string literals from code into strings.xml
1) Move to Fragments for the list view.
2) Switch to CursorLoader from my jankey self-managed cursor.
3) Add session security logic to the ActionBar.
4) Fix colors to be less ugly.
1) Start breaking the UI out into Fragments.
2) Switch to Cursor loaders from managed cursors.
3) Switch to inflated menu resources.
4) Break out some basic functionality into helper classes.
1. New look for quick contact badges.
2. No more unread indicator, replace with bolded text.
3. Style message count with color rather than parens.
4. Remove "New Message" item, add as item in action bar instead.
