* Overhauled biome distribution so that it's less predictable.
* Mountains are taller and have a more natural shape, with innatural shapes being still possible but rarer.
* Made biome much larger; as a result, different climate zones are now farther apart.
* Added 49 new biomes to help with transitions and variety.
* Caves don't breack through beaches, swamps and deserts as often as vanilla.
* Some tweaks to vanilla biomes to make them less boring.
* More natural colors for water biomes; water fog is much darker to make it look less flashy when it's night.
