Subject: [PATCH] [vid] Add an api function to control mouse visibility

It's currently very simplistic (visible, not visible), but it gets
things started for making QF more usable in a windowed environment (not
having a visible cursor was fine in DOS, or when full screen, but not
when windowed (and not actively playing).
