Core/Maps

* Corrected liquid type extraction in maps - MCLQ chunk must be parsed together with MH2O (they stack)
* Fixed liquid detection in WMO objects
* Implemented LiquidType.dbc use, players will now get proper auras in special liquids
* Turned off slime damage by default (Naxxramas uses periodic damage aura for this purpose)
* Implemented liquid type overrides basing on area/zone
* Renamed final temp_gameobject_models to GameObjectModels.dtree (the temporary one produced by vmap extractor remains unaffected)

Note: Map and Vmap re-extraction is required
