* Move site title helper to instance helper (name change only)

This introduces a new per-user preference called
"Auto-play animated GIFs", which is enabled by default. When a
user disables this setting, gifs in toots become click-to-play.
Previews of animated gifs were changed to display the video play
button so that users can distinguish them from regular images.
This setting also affects account avatars in the detailed account
view, which was changed to use the same hover-to-play mechanism
that is used for animated avatars in timelines.
