Mineral floors

For now it will be as is. The mineral floors will be able to be made, albeit for now plasma floors and uranium floors won't do special stuff.

Credits goes to MrSnapwalk for the awesome floor sprites.
you're not.
if these procs aren't needed yet, don't add them yet.
else, make them not copypasted. I don't see the need for 6 copypasted procs that all do exactly the same.
