- Move the support modules inside python3-flightgear/flightgear/ and remove their shebang, if any. - Accordingly adapt the import statements. - Change shebangs from e.g. '#! /usr/bin/python' to '#! /usr/bin/env python3'. - Small changes to make Python 3 happy with all scripts. catalog/check_aircraft.py should be run under Python 3 from now on.
