Title: Add terminal states to TKStateMachine.

This patch adds the ability to specify terminal states for the machine. Once the machine transitions into a terminal state it will refuse to fire any more events. Patch also includes assorted other fixes (like eliminating the use of property setters in -init and transitioning off of shouldBeNil/shouldNotBeNil which are deprecated in Kiwi).
