Alternate Terrain Generation

ATG 0.12.0:

• Fixed flipped x/z coordinates in biome top-block replacement, fixing Mega Taiga, Mesa etc.
• Added a fix for a vanilla/forge bug which makes villages check the wrong location for acceptable biomes. No more villages in the ocean unless you allow them with BoP or other such mods. Villages should now respect the per-biome settings of other mods.
• Added an additional field per biome in biome-modifiers.cfg to disable village generation in specific biomes. This does not force their generation in biomes which would not normally support them, just prevents them generating if they normally would have.
• No API changes, use API archive from 0.11.0.
