Food amount and stuff rebalance 

Jar of canned fruit gives 3 volume back, as it consumes 3.
Bigger mellon.
Nerfed cereal, grapes, cranberries, considering their charges.
Gave strawberry, blueberry jam 1 charge, like fruit jam.
Rebalanced recipes for fruits with several charges.

Rivet handled these already so I'll reconcile 'em with her values.
