Modern Beta for Forge 1.12.2

This major release overhauls the release biome source and implements additional support for several mods. Existing worlds are compatible, but you may want to make a back up first, as usual.

• Add support for Buildcraft Energy. Oil desert and ocean biomes should now generate as expected when using the release biome source. Additionally, you can toggle generation of these biomes when using any non-release biome source in the Add-ons world customization tab. When enabled, the biomes will replace the original ones where appropriate.
• Add support for Thaumcraft. Magical Forest biomes are already supported when using the release biome source, however you can now toggle generation of the biome when using any non-release biome source in the Add-ons world customization tab. When enabled, the biome will replace the original ones where appropriate.
• Add snowyBiomeChance generator option for the release biome source. With this option you can control the ratio of snowy/icy biomes to biomes of all other climate types.
• Update release biome source biome distributions. Hot climates are now more common. They were previously still somewhat rare. Existing worlds using the release biome source will maintain the previous biome distributions.
• Update support for Biomes O' Plenty. Kelp Forest and Coral Reef biomes now generate when using the release biome source.
• Remove useModdedBiomes generator setting, which previously supported just Biomes O' Plenty. Biomes O' Plenty now has its own compatiblity toggle in the Add-ons world customization tab.
• Update certain world customization GUI elements.

Technical Changes

• Add BIOME_RESOLVER registry and BiomeResolverCustom interface. The latter can be implemented and registered with the former to perform granular biome replacements with any biome source.
• Update all lang strings to move them under a mod namespace to hopefully remove possibility of collisions with other mods.
• Update NoiseSurfaceBuilder to move random surface variation sampling to a separate method.
