Description     : This makes the monsters aware of water.  Monsters now:
                    1. Drown if they spend too much time under water
                    2. Swim properly
                    3. Attempt to surface if they are almost out of air.
                  #3 is an extremely ugly hack.  If you have *anything*
                  at all that's even close to decent, send it to me.  It
                  can't be as bad as what I have in there now.
