[10165] New collission system (vmap) implementation

Browse source 
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

Additional Authors:
arrai (DBC handling and indoor detection)
faramir118 (windows support and bug investigation)
And of course thanks Vladimir for a lot of patience and support!
