[Twisted-Python] Bug in twistw.py

[Steve Goldman]

Sorry for posting here, but I couldn't get the bug tracker to register me.

The twistw.py file provided by the windows installers for python 2.2 and
python 2.3 doesn't have any main function.  It needs the following lines
added to the end of the script:

if __name__ == "__main__":
     run()

Thanks.
