Hi,

Needed a python pusher client library for an app I'm putting together, and used yours. Just implemented fixes and changes to make it work. Could you please review to see if they should be merged with the base repository/fork? A demo is available and requires web2py. I can give it locally through teamviewer or another remote view app (python web host does not support websockets yet)...

In all cases, a thousand thanks for the code.
