Append airport code in DLC-GS addresses

Hello,
Tried to enrich DLC addresses, appending the airport code of pointing GS address.
The code is taken from the imported GS database file.

unstable...olyair11:dumpvdl2:unstable

Please check if applicable
Thanks

TBH, I'm not a fan of it. Neither the feature, nor the way it's implemented.
