Comment 6 for bug 1670422

@JP, I know that this will simplify things but I can think of use cases
where the user would want to swap graphical items on other layers.
Limiting the swap to just copper layers seems a bit restrictive and I'm
guessing some users would prefer to use this feature rather than
manually changing the layer for each item on a layer.
