Fixing subtle bug in expanduser(expandvars(path)) on Windows....

Fixing subtle bug in expanduser(expandvars(path)) on Windows. On Windows, some paths can have the string $\ in them: \\server\users$\%username%. The "$" means it is a hidden share. Unfortunately, os.path.expandvars turns that into: \\server\users\%username% (it deletes the '$'). I have implemented a simple function (expand_path) that calls os.expanduser and os.expandvars in a way that preserves th '$' on Windows in this case.
