NEW: Add vanilla fuel and compost recipes to /rmextract
NEW: Compost recipes with full flag, multi-result, and hopper support
Format: <ingredient> % [chance per level] % [levels], where [chance per level] is >0 and <=100 and [levels] >0 and <=7
Both [chance per level] and [levels] can support decimal inputs (meaning you can do fractional levels)
While the composter is being used for a recipe, it will be locked to that recipe (or the same result from another recipe), so no conflicting recipes can be made
Vanilla compost recipes can be overridden/removed
NEW: Anvil recipes with full flag and multi-result support
