Callback dispatch for session events

POESessionMultiDispatch is a drop in replacement for POESession that adds callback dispatch functionality to POE sessions. Each event may have multiple handlers associated with it. Fine control over the order of execution is available using helper methods that extend the interface of a POESession.

POESessionMultiDispatch uses POESession as a base class. When multiple callbacks are registered for an event, only the last callback survives, all the others are clobbered. POESessionMultiDispatch is much nicer to your registered callbacks, it keeps them all in the order they were defined. When an event is triggered, all the callbacks are then executed in that same order unless you muck around with said order.
