File association image for .py

I know it's a little trivial but it's the kind of thing that end users 
really like. Anyone know how to add a registry entry so the .py files 
get a nice python icon in the File Explorer.

I'm assuming that it can be done in the PythonCE.inf for the CAB but I 
don't know the syntax. If someone knows how, I think it should be added 
to the next release.

Thanks,
Alex
