[Twisted-web] Nevow and distrib

[David Reid]

Upon closer inspection proxy.py would need a little work to get it to
work with Nevow and/or new-web.  It returns server.NOT_DONE_YET which
isn't supported by either that I recall.  It also depends on
http.HTTPClient which isn't present in new-web.  

I don't suggest people actually use new-web yet so that's not a big
deal.  But proxy.py should almost definitely add the port (if
present/not '80') to the host header.
