[Pythonmac-SIG] [patch] GetURL argv emulation for py2app 0.5.2

[Brendan Simon (eTRIX)]

Below is my patch to get URLs/URIs to be added to sys.argv when an app
is opened via the Launcher.

It should be applied to:

/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/py2app/bootstrap/argv_emulation.py

Can this patch *please* be integrated (please modify if necessary) in to
0.5.3 release !!

eg.  You can test with "open myapp myurl:test"

The sys.argv attribute should include "myurl:test" :)

NOTE: for some reason the AppleEvent constants kAEInternetSuite and
kAEISGetURL does not work as they are set to 'gurl' (lowercase). 
However using 'GURL' does work :)

Cheers, Brendan.
