Copy Uri.userinfo into Authorization: Basic header
Copy Uri.userinfo into Authorization: Basic header

When making a request, this will take the URI's userinfo
(user:pass in http://user:pass@host/) and put it in as an auth header.
It won't override any authorization already present in the supplied
headers though, and it will only do this for two :-separated fields.
