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

[David Brooks]

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
