greatly simplify consume_feed() - a lot of this was friendica specific and somebody may want to put some of it back in, but we'd be much better off building a zot compatible feed for friendica (hint,hint) - even if it didn't support the other protocol bits. Special purpose feed handlers for things like likes, dislikes, events, and community tags are better handled as zot arrays. We have all those handlers. We just need to pass them a JSON message instead of an XML/Atom message. Handlers for statusnet follow messages are another casualty. That's easy to bring back - but we need to keep driving nails into the XML coffin or the damn zombies will get out.
