Fertilizer Stacking

Another improvement worth noting. It is kind of strange, this will save way more effort in inventory management than milk stacking did. But for some reason milk stacking made me way happier.

@Daguin thanks
@Tagamogi I thought of an interesting way to make cotton for the combined picture, but that's as far as I got. I was thinking if Hector was wielding daggers he would be stabbing the blankets, so cotton would be spilling out. Oh well.
