Have Animations struct handle rooting nodes

Browse source 
Instead of having `ScriptThread` handle rooting nodes, do this in
`Animations`. This makes it easier to know when it is appropriate to
root and unroot nodes instead of relying on a certain order of events.
This also allows reducing quite a bit the amount of unsafe code.
