Fix ALL of the Dom's code!

-Coded in all Stonecutter variants for the new Stone types.
-The new Stone and Deep Stone types are all handled as Stonecutter Raw
variants now, eliminating all of the countless metadata, pick-block,
hardness, and blast resistance problems that occurred with the
originally implemented Deep Stone types.
-Increased the elevation at which Deep Stone variants begin spawning.

-Still trying to fix some leftover bugs, so don't touch anything for a
bit unless you tell me first.
