Add bounds checks to roomdeaths and roomdeathsfinal

Browse Source 
This fixes being able to trigger Undefined Behavior by pressing R when
not in-bounds in the Outside Dimension VVVVVV map, usually when you're
falling upwards towards Game Complete.

I also put bounds checks on normal roomdeaths for good measure. You'll
never know when you need it.
