The default behavior of an event is determined by the entity that calls
into the event dispatcher, so the solution was to unify the dispatch of
these events. Created a utility method in CommandEvent to do that, and
did some singlton-like hackery on the constructor to prevent folks from
thinking they can just dispatch these themselves and have it work correctly.
