New: Proxy with PEP 333-compliant chunked-response support (based on Paste's Proxy class)

[alanjds]

I tried to figure out some bug about partial responses using HostProxy. It occur on requests that works fine with Paste's Proxy middleware. Finally, I found the problem to be the HostProxy implementation of chunked responses.

By some PEP 333 chapter, only the server MAY add chunked responses headers, but it usually does so only if Content-Length is not set. At least Gunicorn seems to do chunked very fine, if no Content-Length is set, AFAIK.

So, I copied over paste.proxy.Proxy code as a new starting point and adapted to use restkit client and to allow streaming of the client response.

This works very good for me. I added no tests, but its working over my blog http://kombobreaker.com/blog

I dont know where the new class should be: wsgi_proxy.py or a new module?
Waiting for your feedback and/or merge.

hi sorry for the delay. It should be another module imo , so the import of paste will be fine. I will try to apply this change asap.
