Title: Add HTTP 407 response for proxy authentication.

It took me a little time to figure out why I was getting 'Unknown HTTP Status', and eventually I found I was getting a 407 response, which Phergie doesn't account for. Behind proxies, a 407 is returned, so it would be nice if Phergie gave the appropriate error.
