Colormatic

This release adds the following behavirors.

• Lava and other fluids can be biome tinted. Cauldrons are not automatically tinted the same as their corresponding fluid.
• Modded and datapack biomes now have a sensible grid format column assignment. They use the column of their raw ID for Optifine resource packs and the column of the vanilla biome closest in temperature and humidity for Colormatic resource packs.
• "palette": { "format": .. } in color.json (palette.format in color.properties) is now respected.
