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.
Important:
* You have to re-extract and assemble vmaps
* Update your config file, new option 'vmap.enableIndoorCheck' added
New features:
* Include WMO+DBC area information for correct subarea identification and indoor check
* Support for WMO liquid (fishing/swimming in cities, instances and oterh WMO based environments)
Technical changes:
* New Bounding Interval Hierarchy (BIH) data structure for better performance
* Referenced model data for reduced memory usage,
needs more files, but reduces overall file size from ~1.9GB to ~550MB
