This is to ensure that when there are a lot of unread messages, the user
is given the chance to see all of them by being scrolled to the oldest
new message.
When a new message comes in, the indicator will be incremented.
When the user sends a message or switches away from the conversation,
the last seen indicator will be removed.

This was supposed to solve the problem of losing group state after a reinstall
by inspecting member registration ids and pre-emptively sending group updates to
those who appear newly re-registered, but it has been unused since 6123c419.
Nowadays there's a protocol for requesting lost group state from other members.

In the absence of a filename, choose something that makes sense.
Display different icons for different media types, including distinct icons

Bind a single listener to keychange events from the storage interface,
which then looks up relevant conversations and adds notices to them,
with tests.
Previously we would need to instantiate a conversation model in order to
start listening to its key change events. In practice this usually
happens at startup but we shouldn't rely on it, and it incurs higher
overhead since it creates a different listener for each conversation.

Sometimes .mov files arrive with content type video/quicktime, but must
be saved to .mov in order for osx to recognize them as videos and open
the appropriate default program, display thumbnails, etc...
// FREEBIE
Make arbitrary files look nicer and display the filename.
If an audio or video element fails to load for any reason, timeout after
a few seconds and render it as an arbitrary file. Also short circuit to
this treatment for common audio and video file types that we know are
going to fail, e.g., proprietary formats from apple.
