* Changed signatures and constructor of MessageDispatcherConfigurator * Changed Dispatchers.lookup, keep configurators instead of dispatchers * Removed most of the Dispatchers.newX methods, newDispatcher is still there because of priority mailbox * How should we make it easy to configure priority mailbox? * Changed tons tests * Documentation and ScalaDoc is not updated yet * Some tests in ActorModelSpec are temporary ignored due to failure
