Added serializer for Namespace's Command and OnData.
Tried to get Namespace as sharding actor.
Removed unnessacery awaitAssert, which requires whole block passed at
onetime.
Replaced DistributedBalancingPubSubMediator with group subscrition supported
Namesapce. Passed SocketIOClusterSPec.
Upgraded to scala-2.11.3
Correct SocketIOTestClusterServer etc.
Fixed Channel for "onNext is not allowed when the stream has not
requested elements, totalDemand was 0'.
The socketio-benchmark now works as expected.
Instruction for run benchmark of 0.2.x
We've combined namespaceMediator and broadcastMediator.
Fallback from scala 2.11.3 to 2.11.2
