Allow *.Cu and *.Mask layers

[kasbah]

Could be a handy shortcut for adding copper and mask to both sides. I think for kicad_mod output we can even use the *.Cu and *.Mask names to get the effect. Not sure on kicad_pcb output.

If I understand correctly...

say you had a feature in the F.Cu layer, but you actually wanted it on F.Cu and B.Cu. rather than copy and paste F.Cu to B.Cu, you could just delete B.Cu and rename F.Cu to *.Cu?

This would be sometimes useful to me in the Mask layer.

i have similar feature in mask layer, if you make the layer name F.Mask-auto it will copy image from F.Cu
