#783820 klonos: Fix warning: copy() [function.copy]: Filename cannot be empty in FeedsParser.inc on line 168.

mapping fail with multiple feed configurations.

Fix accidental roll back of previous commit 'Stop PubSubHubbub from subscribing if it is not enabled.'

Try to add README.txt to front page via @verbinclude. #fail.

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.
