Building in Biomes

Fixes:

Blocks:

-Deepslate Lead Ore is now in the Nature tab

-Command Block shouldn't appear in the Savannah Ruins structure anymore (oops)

Changes:

Blocks:

-Grates now have block culling, so you shouldn't see block faces adjacent to other grates of the same type. Code was borrowed from the Bedrock Wiki.

Additions:

Blocks:

-Added Chiseled Sanctuarium Tiles and Netherrack Pillars

-Added Ectoplasm building blocks, with the same variations as Resin, Honey, Slime and Grape Must

-Added Purple Smoke (purple haze internally). Not craftable nor obtainable for now, still don't know what I'm going to do with it
