Tile Entities Stuffs

Ingot Piles, Pottery and Food Prep properly break and drop only non-ghost items when the block underneath them is broken.
Ingots now act like log piles in that they must be placed on top of solid blocks, or a full ingot pile.
Removing an ingot from the middle or bottom of a multi-block pile results in all ingots above it to fall.
Ingot piles of different metals can no longer be placed on top of each other. (Gets rid of texture rendering issue)

I told ArtyomShegeda I was already working on this code and not to touch it.
You may clean it up now if you wish.
