  Use NSWindow API for changing fullscreen mode

instead of going through NSView's API. The latter does offer more options, but messes up the fullscreen mode for some reason (UI becomes unresponsive because input events are no longer received).

Using `self.window toggleFullScreen:self` also does not mess with additional displays (only the display showing Squeak is put into fullscreen mode).
