Hendrik Leppkes:
    - Fix gathering of micro dungeon data in phased zones, like the Tanaan Into experience
    - Check level parameter for its type to avoid errors when wrong params are used
    - Map the Ashran instance id to the main Draenor instance
    - Add GetUnitWorldPosition(unitId) API
    Note that the unit id restrictions from UnitPosition apply to this API,
    and only a very limited subset of units will return a valid value.
