Interim 2 (#477)

* changed DefaultCancellable.obj with Default.Cancellable and deleted the former (as unnecessary)

* changed ActorRef.noSender with Default.Actor for PlanetSideServerObject entities

* Actor.noSender -> ActorRef.noSender, for consistency

* player name in log messages; zoneLoaded and zoneReload flags; upstream message count

* Default object tests; expanded the set current avatar loop

* fallback cases for unsuccessful zone/avatar load process

* completing the trials of the god Travis

* forgot to reactivate kamon
