First steps on converting FeedSub into the pub/sub basis for OStatus communications:
* renamed FeedSub plugin to OStatus * now setting avatar on subscriptions * general fixes for subscription * integrated PuSH hub to handle only user timelines on canonical ID url; sends updates directly * set $config['feedsub']['nohub'] = true to test w/ foreign feeds that don't have hubs (won't actually receive updates though) * a few bits of code documentation * HMAC support for verified distributions (safest if sub setup is on HTTPS) And a couple core changes: * minimizing HTML output for exceptions in API requests to aid in debugging * fix for rel=self link in apitimelineuser when id given This does not not yet include any of the individual subscription management (Salmon notifications for sub/unsub, etc) nor a nice UI for user subscriptions. Needs some further cleanup to treat posts as status updates instead of link references.
