Refactored the ActivityPub federation layer so it cleanly supports both Create and Update activities, and any future ones.

No change in visible behavior, but internals ready for expanding support. Updates seem to work well.

The devil was in the details though.

webmentions are no longer here, just #activitypub. I am not sure if tags make sense here...
