- Changed implementation of Actor.actorOf to work in the the new world of cluster.ref, cluster.use and cluster.store.

- Changed semantics of replica config. Default replicas is now 0. Replica 1 means one copy of the actor is instantiated on another node.
- Actor.remote.actorFor/Actor.remote.register is now separated and orthogonal from cluster implementation.
- cluster.ref now creates and instantiates its replicas automatically, e.g. it can be created first and will then set up what it needs.
- Added logging everywhere, better warning messages etc.
- Each node now fetches the whole deployment configuration from the cluster on boot.
- Added some config options to cluster
