[10272] Add option for search distance to getHeight() functions and make Creature::FallGround() use VMaps properly.

Browse source 
This finally prevents flying creatures from falling to infinity (basically instantly diappearing) in several instances,
aswell as prevent creatures from falling inside larger solid object around the world.

Default height search is untouched, needs more research on how creature AI etc. will be affected.
