[WIP] Mineral floors

Still busy with it, just making a WIP PR before I somehow loose everything again.

Note to self 2: DO I REALLY FUCKIN HAVE TO REWRITE THE ENTIRE FLOOR CODE TO GET THIS TO WORK!? Aka it doesnt actually make those floors when you, for example, use the uranium tile on the plating. It just resprites the floor.
A tile made out of highly flammable plasma...  
Yet can't be ignited. :fire:
