Permutation of scene graph children

[Werner Lehmann]

Tom,

I know about Collections.swap but it looks like a bad idea to use on 
scene graph children because it seems to temporarily have a duplicate 
element in the list and I can't have a node twice in the scene graph. 
The setAll approach is what I am using now but native permutation or 
swap support would be better because it does not remove/add nodes, 
triggering CSS and possibly some listeners on scene or parent properties.
