updates, cleans up and finishes the remaining Plasma::RotationStackedAnimation transformations. Now every combination of animation origin ( Up, Up | Left, Up | Right, Down, Down | Left, Down | Right, Left, Right) works with the animation movement directions ( MoveUp, MoveUpLeft, MoveUpRight, MoveDown, MoveDownLeft, MoveDownRight, MoveLeft, MoveRight).
