Bug: disable sort slider during animation
Bug: disable sort slider during animation

Rapidly clicking on the slider causes the state to be corrupted while
rendering. Disable the sort slider when animation is active and
re-enable it when the animation is done.

- Enhance toggleHostGroup to accept a callback
- Enhance reset to accept a callback.
- use callback to resolve a deferred at end of animation
