Difficulty Mining

Adds new blocks with nice textures which make mining more interesting including:

- A new dirt type that effects the miner with poison if they are using a inefficient tool
- New stone type that spawns silverfish on being mined without silk touch
- New polished variant of said stone
- New naturally spawning compacted dirt
- New zinc stone that spawns a multiple zinc infused silverfish
- A underground compound that explodes upon being mined with a non diamond tool
- Zinc tools that are slower than iron but more durable
- A zinc power you can eat to gain resistance
- New fake diamond ore that looks slightly different and does not drop any loot
- And zinc can be formed into zinc plates for stairs, walls, and slabs

Let me know whatcha' think!
