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.
