Clean up font management

Default to b.userName instead of message->account()
Made font updatable in the Settings dialog with a font dialog
More work on subscription badge loading

Known issues:
  - Font isn't updated in a split until a new message is written in that split
  - When font/font size is changed, old messages don't have their size updated causing weird layout of old messages
