APTLoader: rename member 'currentAirportID' to 'currentAirportPosID'

Browse source 
This will be clearer since it is a PositionedID and we are also dealing
with airport identifiers in the sense of the apt.dat spec in the same
class.

Rename 'line_id' to 'rowCode' in src/Airports/apt_loader.cxx

"Row code" is the expression consistently used for this number in the
apt.dat format spec. Since we already deal with airport *identifiers*,
this should make this piece of code easier to read.

For the same reason, rename the 'num' parameter of
APTLoader::parsePavementNodeLine850() to 'rowCode'.
