HM3: Capes

With thanks to Imp and others for pointing out the lack, I've added in 15 new cape backs to the "Backplane-Standard" set, for the most part designed explicitly to go with the items in "ShoulderRight-Capes":

Hope you like 'em. If you see something out of whack, or have a cape back you were really hoping for but which I didn't draw, let me know.
