add event as argument to onEntry(), onExit() and onTransition()

Accessing the event can be useful. E.g., onEntry() can do some
common event processing regardless of which transition caused the
state to be entered; onTransition() can be used in combination
with eventTest(), where eventTest() would first check that the
input matches some criteria, and then the actual processing of that
input would be done in onTransition.
