Hendrik Leppkes:
    - Add an allowOutOfBounds parameter to GetPlayerZonePosition
    This allows retrieving a valid position from GetPlayerZonePosition if the
    player is outside of the visible map area, but still considered inside the
    zone.
    - 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.
