- break OMB profile update pings to a background queue

- add event hooks to profile update pings
- send Salmon pings with custom update-profile event to OStatus subscribees and groups (subscribers will see it on your next post)
- fix OStatus queues with overlong transport names, should work on DB queues now
- Ostatus_profile::notifyActivity() and ::notifyDeferred() now can take XML, Notice, or Activity for convenience
