Subject: Only call OSystem::updateScreen() every other frame, so no more than
 50 times per second. This doesn't appear to make a visible difference on PC,
 but allows the game to run on PSP and probably several other consoles/ports
 that wait for 50/60hz vsync. Since I'm not familiar with this engine I've
 added a 'FIXME' comment, because maybe this can be fixed/improved in a
 different manner.
