MS Orleans style virtual actors

[rogeralsing]

I'm currently working on MS Orleans style virtual actors.
This is implemented the same way as they do in Orleans.

This allows you to do massively distributed systems without having to care where and how actors are created.

func main() {
	cluster.Start("127.0.0.1:0", "127.0.0.1:7711")

        //get a PID to your virtual actor, the cluster module will find or register it's existence for you
        //on one of the nodes in the cluster.

	pid := cluster.Get("myfirst", shared.Type1)
	pid.Tell(&shared.HelloMessage{})
	console.ReadLine()
}

Currently, this support covers:

• Registering actor types
• Look up actors by ID
• Automatic placement of actors

Some features need to be implemented:

• Passivation of idle actors, this should be doable with a pipeline plugin
• Joining nodes need to take ownership of some actor lookups from nodes on the left and right of it.

Joining nodes need to take ownership of some actor lookups from nodes on the left and right of it.

This have been implemented.

Typed Grains are now generated via Protobuf protoc compiler.
