Add a symmetry function that allows us to mirror an object over a common center.
Obviously this will help us do things like making arms and legs.
I'm not sure how to resolve this simply without also adding a mirror plane of some sort or allowing multi-selection...
I suppose if you keep the current behaviour of affecting all children at once in most operations one solution would be to mirror across the pivot of the parent object with a mirror x, y, or z function. If you also resolve reparenting not moving objects we could then use dummies for mirroring where necessary.
