[patch from Kelvin Delbarre] If you move the mouse cursor in and out of the

SheepShaver window a number of times (somewhere around 30 or 40 times will do
it), SheepShaver appears to lock up. This occurs because SDL posts application
activate/deactivate events to its event queue when the mouse moves in/out of the
SheepShaver window, but these events are never consumed, and as a result, the
event queue fills up. Thereafter, no new events can be posted, and user inputs
are ignored. The fix is to consume SDL_ACTIVEEVENT in handle_events().
