embedded python pythonpath

[Furkan Kuru]

Actually, I do not want any .py or .pyc files around my executable.
(including userdict, sys, site etc)
I want to have just single zip file for all python files.

I had a look at py2exe source codes but could not figure out how it just
looks into a zip file.

So maybe I have to compile the svn version of python.
