MustardMustard Pack

Removed Journeymap - didn't feel really vanilla-like. Instead, added the atlas: a craftable mapping system that is viewed on a special book. 

Added a new dimension: The Abyss. A craftable dimension with loads of new mobs, block, and bosses. *Completely optional* I consider that minecraft deserves a new dimension added to the game, and this mod seems to do that perfectly, with loads and loads of high quality content.
