- 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
