Extra tiles

[Proxima]

I recently added these tiles to the NeoLemmix version of my tileset. Do we want to have them in Lix as well? One problem is that the NL versions are scaled down so that each pair of tiles has a 32x32 and a 16x16, but for Lix we would want them to be 64x64 and 32x32.

I'll try to add nubs to the steel, to make the steel look different enough from geoo's construction concrete.

I'll give you feedback before I add anything to Lix. We can then decide what's the best look. Prod me if I haven't gotten back to you after the next weekend!
