  language, user properties from parent feed node. Note: Signatures of
  FeedsProcessor::map(), existingItemId(), FeedsParser::getSourceElement()

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

Basic auth can be used by supplying URLs like http://user:pw@example.com/feed .

basic auth credentials for a series of feeds in a single spot. Will post this patch
on the issue queue for further consideration.
