- UI (previously MainUI) is back to being the only component loaded
as Window's child
- UI has the background image previously only for the SignInPage
- If there are no accounts, the UI Loader's initialItem is the
SignInPage
- The SidePane becomes visible when there's >=1 account connected
- Standardized capitalization for variables and file names everywhere in
QML and JS, get rid of mixed camelCase/snakeCase,
use camelCase like everywhere in Qt
- ListModel items are now stored and returned as real QObjects with
PyQt properties and signals.
This makes dynamic property binding a lot easier and eliminates the need
for many hacks.
- New update(), updateOrAppendWhere() methods and roles property
for ListModel
- RoomHeader now properly updates when the room title or topic changes
- Add Backend.pdb(), to make it easier to start the debugger from QML
