Add animation components

Three levels of animation playback are available at present for
keyframe animation:

1) Direct playback of a clip via QClipAnimator
2) Playback of a blend tree of clips via QBlendedClipAnimator
3) Playback of a set of blend trees controlled with a state machine
   via QConductedClipAnimator

This commit adds the frontend and backend nodes for all 3
components and registers them. The blended and conducted animator
components are just empty skeletons for now.
