introduce AkkaApplication

Browse source 
- remove global Config
- pull everything which depended on it into new AkkaApplication
- leave EventHandler alone for the moment: that evil sucker gets his
  very own AkkaApplication("akka-reference.conf") until we have settled
  on an acceptable logging API without globals
- make akka-actor and akka-testkit compile
- TestKit uses implicit AkkaApplication passing for maximum convenience
- Actor object nearly completely removed, actor creation possible via
  ActorRefFactory interface which is implemented by AkkaApplication and
  ActorContext
- serialization of ActorRef is probably broken, and so is the reflective
  RemoteSupport (now needs AkkaApplication constructor arg)
- everything else is still broken, including akka-actor-tests, so this
  is of course all not runtime-tested
