Previously, libtextsecure would send a sync message automatically
when appropriate. This fails if any recipient has a key conflict
or if our network connection fails mid-send.
Instead, when appropriate, return a the DataMessage encoded as an array
buffer for later syncing. This lets the application choose when to send
it, which we now do after any successful send to a recipient, rather
than after all recipients are successfully sent to.
Eventually we should move the DataMessage protobuf construction and
group sending logic to the application layer entirely, in which case
we wouldn't need libtextsecure to construct the sync message either.
Fixes#408
Fix bug where re-installing would cause sync messages to fail and
produce unresolvable error indicators on messages that were actually
sent.

If you had an inaccurate unread count due to previously broken unread
tracking, it's possible to go negative and never fully recover. Fixed
by clamping to zero.

Messages that are received in the active conversation while the window
is focused, are automatically marked as read.
The conversation appears as unread for a split second as the incoming message
arrives but it gets marked as read as soon as the message is displayed.
The window title now shows the global number of unread messages as
"Signal (1)". This way the user can see the number of unread messages
in the task bar and when alt-tabbing.
Resolves: #384
Fixed the global counting of unread messages. This makes the "unreadCount"
variable in storage to stay in sync with the sum of unread messages in each
conversation. To achieve this, the controller_view updates the global
variable whenever messages are received or read.
encryptMessageFor now requires an array buffer instead of a protobuf.
By converting the message to an array buffer outside the Promise.all, we
avoid allocating a new copy for each device.

We don't need to keep them in memory if we're done viewing them,
plus it avoids having to re-render a large collection when we re-open a
conversation. Now that we only load a sensible number of messages at a
time, caching them between usages is less valuable. Removing them from
the collection should free them for garbage collection.

Messages with images or media were causing the scroll position to jump
around when they loaded, because rendering them changed the height of their
elements from 0 to full-height sometime after they were inserted into
the DOM.
Now when rendering attachments, we wait for them to load so they can
render at full height immediately, then warn our parent message list
before and after a potential height change, so the scroll position can
be saved and reset.
// FREEBIE
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.
// FREEBIE
Add db adapter support for clean cursor termination when passing
options.index and options.limit together. Previously this would cause a
crash because options.conditions was undefined.
// FREEBIE
Bubbles are limited to 30em to facilitate comfortable reading length.
The width of the message list is limited to aid visual threading
of the conversation. The overall layout is restricted to 1300px and
centered if the window is much wider.
The header avatar resizes responsively to save room when the window
gets narrow
