Added a void to separate the cave world from the root world. (#833)

* Add files via upload

* Move the files because I love github

* ACTUALLY replace the files. I love github

* Changed it to 50k

* Folder for void biomes + other changes

Made torches rarer,
Fixed void caverns generating too high,
Made the fog lighter,
Added a root crystals biome (it's a bit rare, I haven't seen it generate, but hypothetically it should be there)

* Removed air patches

* Various Void Changes

Made void spawn lower,
Made void root torches more common,
Changed fog color

* Fixed Fog Color and Made Fog Thicker

* Made the void 1500 blocks tall

* Added caves parameter to Void

* Removed stoneblock replacement
