Added working(ish?) code for closing the nvidia-settings app on MainWindow close:

- Modified close_request() function in MainWindow class to check if any Cancellable objects on stack
- Added Controller object creation to open_settings() function in Provider class
- All commented for now - app doesn't respect the "cancel()" call
