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
- Remove some underscore-prefixes
- Start using this-> more
- Remove a few of the singletons (We pass references to managers to
things that need it now. Might not be much better, but for now
it works. It also shows what places might be slightly wrong
designed)
