Access to publish through Celluloid class method.

Mentioned in IRC to @halorgium: IMO, a class method interface to publish messages ought to be accessible from outside actors, through a class method on Celluloid, just like Futures have such an interface.

For example, Celluloid.publish() or Celluloid::Notifications.publish()

My comment about synchronicity was unrelated to this feature request. :+1:

Totally wrong repository.
