Medan Airport shifting and subsequent inaccuracies

Medan Polonia Airport has been closed to all civilian traffic wef last year 2013, and converted to a military base with the IATA code WMK; bringing its civilian traffic to Kuala Namu International Airport.

Hence, the code (MES) for Polonia should be changed to (KNO) - that for Kuala Namu, as well as the coordinates. Other data should be edited but I think this is the most pertinent to be done first.

Thanks!
