Hungry Waters

Changes

• Piranhas spawn weight is increased significantly when Aquaculture is installed (Aquaculture's fish spawn weight are very high and were preventing piranhas from spawning), now they compete equally.
• Hardcoded supported biomes for spawning piranhas have been removed and the mod now relies on the #c:is_swamp or #c:is_jungle or #c:is_river to spawn piranhas. This makes piranhas able to spawn in any modded biome that properly uses tags (which is the case for pretty much all the ones I've tested).
• Piranhas will no longer spawn in cold biomes (marked as #c:is_cold)
