OStatus cleanup...

* Treat linkless feed posts as status updates; drop the "New post:" prefix and quotes on them.
* Use stable user IDs for atom/rss2 feed links instead of unstable nicknames
* Pull Atom feed preferentially when subscribing -- can now put the remote user's profile page straight into the feed subscription form and get to the right place.
* Clean up naming for push endpoints
