Added Config, Fail Metadata for Darkstone

Made page for Block IDs, so they can be changed via config file. Not
sure if config works yet, but the game runs with the new setup. Also:
Presently, there are 90 IDs! XD

Tried to get all variants of Darkstone (cracked, smooth, etc.)
functioning as metadata blocks, but have only succeeded in removing
Darkstone's name. Game runs. Will try commenting out the various
darkstone blocks. (Maybe the unlocalized names are conflicting?)

New dimension still not working (fails to generate anything but bedrock,
and that only after a crash and re-open; teleports to void world instead
of Overworld; no wait time for portal teleport), and so is commented
out.
