(Gestures) Use the actor-gesture-data containers and use raw Actor pointers.

(Gestures) Use the actor-gesture-data containers and use raw Actor pointers.

Use the containers provided by actor-gesture-data rather than checking if the actor

Using raw Internal::Actor pointers instead of handles.
Removing unnecessary templates.

Next step is to remove gesture-processor functors and use deriving methods instead.
