Overhauled the biome generation and id config files, redid biome registration/referencing and made the mcmod.info have alphabetical ordering because it was irritating me. In turn, you no longer have to pick a biome from every temperature type, generation of biomes added from the default world is now configurable (closes #239) and disabling special biomes should no longer cause any issues.
