Added a ServerWindow::ScreenChanged() hook, which takes care of resizing

an eventual offscreen directwindow and sends the direct window notifications 
(not yet, though, since a BDirectWindow on a non-visible workspace would
get the B_DIRECT_START notification and start drawing on a different workspace).
