Dev news : started adding copper blocks to RA (Patreon)

I have laid out the foundation for copper-related blocks, here are two variants (regular and exposed copper block). The rest should come pretty soon as I made the current block to be procedurally customizable so I should be able to design the rest fairly easily.

Those screenshots are renders, but when the remaining blocks have been designed (copper block, cut copper, and their oxidation levels) I'll show in-game screenies as well!
