Simultaneous moves

Removing the wontfix.

Roofpig has this, but I don't like combining moves using +.

I'm currently thinking that it should be alright to detect of if all moves within a group (parentheses) can be animated at once. Then animate those together. Looks clean and natural, and not a hard problem for most twistypuzzles (i.e. for cubes, it just requires checking if all moves are on the same axis).

We have a SimultaneousMoveIndexer since a while, but it only works with Cube3D and still needs to be combined with the (efficient, default) tree indexer.
