Slings, stones and latex

Slings, a sort of weapon which can be used for beginners. Its durability is lower than a bow and it deals lower damage. Slings can be crafted with 6 sticks and a rubber band (which can be obtained by crafting a string and latex). Stones will be the ammunitions for the sling. Stones can be found on the ground (grass, dirt...),placed like candles or sea cucumbers. Breacking cobblestone may also drop stones. Unbreackable 1/2/3 will be the only enchantments that can be used on slings. Latex will be dropped by cutting a new specific tree.
