Grown biomes

Added new biome generator, this one looks really close to Vanilla.
Tasks:
- [ ] rare biomes (mesa, sunflower plains, ...)
- [ ] biome edges (extreme hills edge, jungle edge, ...)
- [x] the biomes generate too large
- [ ] there is no configuration for parameters that could be configured
- [ ] the jungles are too large
- [ ] the ice plains are too large
We need a better way of generating these switch statements.
How about a json file which could be parsed by a lua script and the functions auto-generated.
