Roll back HTTP Basic Auth UI support.

Basic auth can be used by supplying URLs like http://user:pw@example.com/feed .
The authentication in URL approach is powerful enough for most use cases. The only advantage
that the UI that is about to be removed here would have had is that it could change
basic auth credentials for a series of feeds in a single spot. Will post this patch
on the issue queue for further consideration.
