[Pythonmac-SIG] Allow multiple executables in a single py2app bundle

[David Brooks]

Resending, as didn't make it to the list when sent on 18 February...


Hi,

The following patch enables the name of the stub executable to determine 
the Python script to run. This allows multiple scripts to use a common 
runtime.

Required manual steps are to make copies of the stub in ./MacOS and to 
copy the actual Python scripts into ./Resources.

N.B. The py2app/apptemplate/prebuilt contents need to be recreated by 
running 'python setup.py build' in py2app/apptemplate, before running 
the main 'setup.py install'.


Enjoy!

Dave
