* vehicle accessories now get moved with their vehicle
* try to account for multilevel zone offset nonsense
* fixed some more typos and unaccounted null cases
* Entities (Objects, NPCs, ect) can now easily be assigned to a different map to be displayed on by clicking their pip on the map
* Entities with already assigned area (by TrinityCore) that were unable to be matched onto the map are no longer discarded. They'll now show up in appropriate listviews.
* Entities without already assigned area that are also unable to be matched onto the map now get an area assigned as long as the relationship areaId <=> mapId is unique (read instanced areas)
