Title: Codechange: Change the palette rather than the image when recolouring.

As a first step towards adding free graphics, trying to get rid of this image copying function.
Palette copying should be cheaper as well, which is why I think it can be added now.

I ran a small test where I checked for colour of the clothes in both cases, and they were equal.
