Add 320x200 screen bounds checking to Operation Stealth's checkCollision function.

Fixes teleporting bug when getting out of the water after first arcade sequence.
The player previously got teleported to the beach near the hotel. Now it doesn't happen.
The player is still caught motionless and can't move after this fix though...
