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.

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.

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

Change how message errors are rendered. Errors associated with a number
will be shown under that number in the detail view rather than piling up
in the message bubble.

This will change the text color of outgoing links from blue
to gray to increase the contrast to the background color of the
outgoing message bubble. Also, the text selection color of these
links will be the same as for normal text.
This will change the text color and the background color of selected
text in outgoing messages to make the selection more noticeable.
::selection and ::-moz-selection have to be seperated into two
selectors because browsers will ignore selectors with partially
unknown syntax.
Makes the groupupdate and recipient input fields stick to the top,
restyles the typeahead as a floating dropdown list of suggestions
rather than a full width component, fixes group avatar thumbnail
rendering.
// FREEBIE
Establishes basic functionality for viewing conversations in two column
mode, including message area and message list resizing, and maintaining
scroll position.
Various subviews need to be retooled but are more or less still
functional, i.e., new message, message detail, key verification, etc...
* Fix a css bug preventing bottom bar from sticking to the bottom.
* Resize discussion container as a function of the overall window
height. The previous difference-based method gives the wrong result
when the window height changes but the bottom-bar height stays the
same.
// FREEBIE
On the conversations list, if the last message is too long, cut it with ellipsis (...) instead of going out of the screen.
On the single conversation view, if the message in the bubble contains a word that is longer than a bubble, break it anyway instead of going out of the screen.
