Title: Add Proxy Authorization Support

A new class is auth.py add the `Proxy-Authorization` header to a Request object.

If a proxy is specified in the request, the `send()` method is going to look for authentication info in the proxy URL string and set up the proxy auth from there.

None of this works with out the changes to urllib3 in #293, however.
