The RoomWidget connects to and displays a single yaboli room.

Its life cycle looks like this:
|
|
1. Create widget
|
|
2. Call connect() (while the event loop is running)
|
|
3. Keep widget around and occasionally display it
|
|
4. Call disconnect() (while the event loop is runnning)
|
|
5. When the room should be destroyed/forgotten about, it sends a "close"
