Android: Differ between ShowMaximized and ShowFullScreen

The default is now ShowMaximized which behaves as it did before,
i.e. each window will fill the screen but the status bar will be
visible. Calling showFullScreen() explicitly will now hide the
status bar to maximize the amount of screen real estate occupied
by the application.
