8020: Cavern tiles

The cavern tiles are copied here by the routine at 8684 and then used to draw the cavern by the routine at 8A75. The extra tile at 805F behaves like a floor tile, and is used as such in The Endorian Forest, Attack of the Mutant Telephones, Ore Refinery, Skylab Landing Bay and The Bank. It is also used in The Menagerie as spider silk, and in Miner Willy meets the Kong Beast and Return of the Alien Kong Beast as a switch.
