OSGi Changes WIP

Hi Mathias, as requested.  There are some changes in here you're not likely to want, for instance the publish location, but I'm not skilled enough with SBT to know how to make it work for all cases.  Sources upgraded to Akka 2.2 in order to get ahold of the ActorSystemActivator.getActorSystemConfiguration call, but unfortunately the scheduler is now removed from ActorRefProvider, needs to be fixed in UnregisteredActorRef.
