[x3d-public] Turning on and off simultaneous animations individually

[Andreas Plesch]

Both x-ite and x3dom behave the same. Each animation is independent and
resets individually after it is stopped and then restarted.

It seems you aim for another behaviour with some dependency between
animations.
