automatic area switching

[Niko Sams]

Hi,

I'd like to implement automatic area switching for the debugger.

1. How can I switch an area?
IUiController::switchToArea creates always a new MainWindow, and
showArea is not in the interface.

2. switch back:
- should we switch back?
- if so - when?
It could be done when the debug session ended. However the user won't
see the output in the Debug Tool View then.
So it's probably best to leave switching back to the user.

3. (different topic) making the editor ready only during debugging.
- do we want this?
- while debugger is running, or just in the Debug area?
