that will detect an __main__.py or __rawmain__.py in the application bundle.
This file is then exectued as the main script. We now have applets in
MachO Python!!!

The difference between __main__ and __rawmain__ is that the former gets a
complete simulated argv (so you can drop files on the applet and the script
sees them in sys.argv) while the latter skips the argv simulation and the
<option>key dialog. This keeps the AppleEvent that started the app intact,
as well as the funny "-psn_xxxx" argv[1] argument, so the script can do
with these what it wants.
