[aprssig] Airport designations

[Steve Look]

I don't know if this has ever been brought up before but it occurs to me 
that the "geoname" could be a local airport name. As an example; around 
here we have Springfield = SPI, St. Louis = STL, Champaign = CMI, 
Bloomington = BMI, Decatur = DEC. Little towns with little airports get 
some weird ones; Lincoln = AAA, Monticello = 2k0. It may be best to use the 
closest big airport and then the -1 -2 -3 -4 to indicate relative position 
from there. Lots of places to look these up online.
