Renamed KIFTester to KIFTestActor.
Move responsibility for actor creation from TestCase to TestActor.
Move common tests to KIFTestActor.
Separated out KIFTestActor behaviors into full subclasses. This will allow for the creation of non-UI, non-system actors without creating a monster actor. (Things are planned.)
Fixed Testable example. Fixed defect in KIFTestCase.
Fixed Calculator example.
