Fixed the following issues:

--> Animation of Bricks. Animation was previously executed on the false View instance, this is fixed with animation listeners and state pattern in bricks
--> badTokenException for the 2 mentioned SetLookBrickTest tests has gone, I guess it was because the same view was used before all the time. Now it's fixed, see Jenkins testrun:
