0.1.5.1 Add more compostable items to Compost bins (moved from Subsistence repo)

[valsnoisytoys]

• fruit
• uncooked garden products (wheat, potatoes, carrots, etc)
• leaves (are they in already? didn't test, I should have... sorry!)

Even if you have to put a lot in to get 1 dirt (eg a stack of apples), it'd be lovely to have more ways to make dirt.
