Mortar & Pestle

Changed up how the Cannibalism effect works. Now it is a chance per tick to advance to the next stage, with a guaranteed  progression once a designated time is reached. Stage 4 is eternal now, more deadly and has a small chance (5% per 20min) to cure itself. Food items no longer give INTEGER.MAX_VALUE duration, but 5min.

Improved Flint Hatchet mining speed to be actually usable, but reduced durability.

Removed raw_human_flesh from the player loot table and villager loot table, as it caused issues with drops when paired with some mods. If I find out how to do this better, they might be re-added.

Finally added the recipes for the copper tools plus one for better usage of the sulfur crop.
