Useful Stones

*Added prismarine tools (and the Glimmering Prismarine Shard you use to craft them)

     -Prismarine is better than iron and worse than diamond in all aspects but enchantabilty, in which it is better than both

     -Made cool animations for this as well as a secret item

*Adjusted tool values balance the stones around each other

*Tried and failed to understand blockstates. Will attempt later (hopefully the correct way).

*Tried and failed to allow the mineral stone pickaxes to be repaired via anvil with their respective stone type in an efficient manner, code-wise.
