Draft: Implement user account indicator/switcher in main view
This MR fixes #236 (closed), by placing a combo-box at the bottom of the rooms list that displays the account currently being used.
Technically, this feature is already in, but it is hidden because of a bug, which can be fixed by removing this line. It works, most of the times, but it does not look great (IMHO):
My artistic sense is non-existent, but I feel that showing the full name plus avatar in a combo-box looks better and is more intuitive:
Unfortunately I have no idea why the avatar image does not load, hence why the Draft
status. I'm still investigating this, and any hint is appreciated!
