Additional Textures

I feel like the pack could use more textures. Some ideas:

-Broken stone/brick: the cracked alpha doesn't look quite right, plenty of other packs have broken variants.

-Lava natural rock variant: The gold rocks make great lava rocks too.

-Some wooden/carpet textures in Dwarven style. Not everything has to be lavish and decorated, for poorer areas, or miner camps/scaffold structures.
