[BUG] FSPackagetool fails to report erroneous info in aircraft.cfg and crashes on building

I was unable to build my package as the PackageBuilder was getting stuck at
the “Preparing commands for asset…” step. The culprit was a typo I had in
the aircraft.cfg: atc_parking_codes=“#DEICETYPE#_#DEICE_ID#” This was an
illegal entry that I caught by comparing the latest PackageSources folder with
a previous build. It would be very handy if illegal syntax like that was
reported in the console, even without stopping the build process.
