Make #matrix public rooms bold to make them stand out from the other public rooms. Ideally this would be metadata in /publicRooms to say something like 'featured channel', but for now, just make it a client side check.

 - do one and only one initialSync when the app starts. (recents-controller does not do its own anymore)
 - initialSync: get only the last message per room instead of default number of messages (10)

Prevent recents-controller from loosing its data each time the page URL changes

Use the room_display_name when presenting on the home page, and not the room_alias which may not be set.

This reverts commit c3f9d8e4.
