Split this mod into a set of sub-mods in a modpack, and in the process did a whole bunch of renovations. * updated Subterrane's API to allow for more patterned placement of things * added "warrens" * clean separation of flooded and non-flooded caverns * rearranged biomes to make cavern layers more distinct * added oil layer * added underworld layer
