I might have gotten a few aspects of the composting process either wrong, or reversed.

• Compost does not become Mulch. Organic mulch can decompose, but its role is otherwise distinct from compost;
• Compost will eventually become a rich, fertile soil;
• Compost enjoys sunlight better than shade;
• Moisture and fungi are good assistants to decomposition.

As such, changes are being considered to both the composting process and the blocks/items themselves. These might become breaking changes, unless we can successfully use a Forge event to substitute old block mappings for new ones.

Changes to be decided:

• Organic Compost will retain its name, and have 8 stages of decomposition (thank you, @LordGrimmauld!)
• Mulch will be renamed to Rich Soil
• Compost will either not decompose at all, or do so slowly, if lacking ideal conditions:
  • Compost Activators 1 block above or to the side
    • Mushrooms, podzol, mycelium, other compost and mulch
  • Moisture (water sources, but they won't hydrate the block itself)
  • Light (compost likes heat. actual sunlight or any source?)

A tag might be nice to keep all blocks meant to "activate" compost, I'll add one to the compost branch.

Done! Earthworms have been delegated to a later update for testing, but everything else above is complete.
