[PATCH 4/8] Use Proxy-Authorization instead of Authorization for proxy auth

[Clément Bœsch]

When using http_proxy, the authentication header is not correctly set:
it uses the same "Authorization" header as the http one. Here is a patch
to adapt the behaviour with proxies (thanks to Louis Opter
<kalessin at kalessin.fr> helping me pointing out the issue).
