Implementing IPersistStorage using PythonCOM

[Mark Hammond]

IPersistStorage is pretty badly broken when trying to implement it from 
Python. A really obvious error in PyGPersistStorage.cpp.

I have fixed it here, but not too sure how that helps you - if you are 
building from sources, then you can simply get a new CVS update and 
rebuild.  If you aren't I could try mailing you a new pythoncom20.dll
