Better Caves and More

This is a mod to make caves more interesting, as I have always found them a bit dull, it adds stalactites, vines, mud, bats, and cave salamanders! You can also make rubber boots to move faster in mud, made by making a sap bucket, tapping a rubber tree with a knife, collecting sap from a rubber tree, then smelting it into rubber. Stalactites generate in every biome but Icy biomes, Rain forest, swamp, and desert. Icicles generate in Icy biomes, Vines generate in Rain Forest and swamp biomes, and Mud in swamp biomes.
