Updated the statechart and state class to now include logic that checks if they can respond to and event
tryToPerform has been added to the statechart mixin
The state's tryToHandleEvent method now checks if an event handler returned the value NO
statechart's sendEvent arguments have been made to be more generic. Now arg1 and arg2
Updated framework's tracing functionality to improve debugging statecharts
removed the try-catch block in statechart's sendEvent method. Was an old hold-over that is no longer useful
Updated framework to simplify the construction of a statechart
refactored logging logic for tracing, errors and warning messages
added invokeStateMethod to the Ki.StatechartManager mixin
Added firstCurrentState computed property to Ki.StatechartManager mixin
Updated the gotoState error message when attempting to transition from one state to another state where the pivot state's substates are concurrent
Added destory logic to both Ki.StatechartManager and Ki.State
Improved the trace and owner feature so that the properties representing them are no longer fixed. Can now use special key properties to change what owner and trace properties to use
Added feature to statechart to suppress warning messages produced by the statechart
Enhanced Ki.State.plugin feature so that it can optionally be provided hash objects that get added to a plugged-in state upon creation.

Refactored Ki.StatechartManager mixin logic. initMixin is now part of the initStatechart method
Added Ki.HistoryState that can be set as the initial substate
Updated Ki.State toString method. Now provides a better string representation for debugging
Added fullPath computed property to Ki.State
Updated Ki.StatechartMonitor's toString method

Updated statechart logic so that if a state's initialSubstate is not a value then the default state used will be an empty state (Ki.EmptyState). A root state must always have its initialSubstate property assigned an explicit value.

Added advanced event handling functionality to framework
Fixed issue with enterState being called before the state is considered entered [Colin Campbell]
Updated statechart so that you can plugin the root state just like any other state using Ki.State.plugin
Updated framework to notify when the statechart's current states have changed and when a state's isCurrentState property has changed.
