Frank's Great Fall update

This was an interesting update process for me. I struggled with getting the swimming levels to play nice with the other levels and with each other when switching scenes. Needed to redo the scripts completely multiple times and even scrapped 4 days of work.  After all that I think I produced something promising.    There are three swimming levels that are now playable (you can swim around, run out of air, see the pretty fish.  Now off to develop the fish attack scripts.
