Make dividers width match the wider ones in expandable lists

Also clean up announcements and profile some
Don't create a new fragment if we're changing orientation
Improve title handling when changing orientation in search
The request activity actually jumps us to the torrent that filled the request, so add support for that

The comments fragment will now start loading when the view is created if the user's logged in. We also load the first 2 pages of comments instead of just the first one.
Better handling of loading failures for torrent groups & torrents
Migrating Profile Activity over to an AsyncLoader

Also have made it more fragment focused and improved handling of orientation changes. The AsyncLoader will also detect cases where we've been rate limited by the API and will sleep for a bit before retrying to load the profile
Be more strict on checking the rate limit message and more descriptive error loading feedback
Improve rate limit retrying in comments as well

Also check isAdded instead of seeing if a view isn't null since they'll mean the same thing.
