Fix mouse cursor moving to fast in fullscreen GUIs (main menu, PDA)

Browse source 
The fullscreen guis pretend to be 640x480 internally, also for the mouse
cursor position. So adding the actually moved pixels (when playing the
game at a higher resolution) to the GUIs cursor position makes it move
too fast.
To fix that I detect (hopefully that check is reliable!) if the
idUserInterfaceLocal instance is a fullscreen GUI and if so scale the
reported mouse moved pixels with 640/actual_window_width and
480/actual_window_height.
