Hunger Overhaul - 1.0.0

• Made max exhaustion level blank-slate-able
  • Used the already existing hungerLossRatePercentage config option to make max exhaustion level = 3 still the default
  • Made difficultyScalingHunger adapt to the hungerLossRatePercentage setting
• Made chestLootMaxStackSize default to 16 (down from 64, which was insane)
• Fixed float/double config options using the wrong default minimum (fixes things like foodHungerToSaturationDivider=0.0 causing food to have infinite saturation)
