CutieDrops

Added the ability to specify drop chances for different items

Example:

drops:
  # Normal drops when transforming mobs into babies.
  # One of:
  #   ENTITY: MATERIAL                    — always that item
  #   ENTITY: [ A, B, C ]                 — equal random among listed
  #   ENTITY:                            — weighted random (numbers are relative weights)
  #     MATERIAL_A: 80
  #     MATERIAL_B: 20
  CHICKEN:
    FEATHER: 95
    DIAMOND: 5

• Removed messages about transformations and other events; only system messages remain. Players now only hear a sound.
