Nyancats are independent in the default mod. Nothing else uses them or their code. Separating it into a separate mod makes it easier for subgames to remove them. It also makes it easier for a mod to depend on nyancats, as lots of subgames don't have them. Default/mapgen.lua: Register biomes, ores and decorations in singlenode mapgen. These were never disabled anyway because singlenode was removed from the world creation menu.
