Changes

Fix boiling not doing anything in cauldron fill recipes

Fix config key

Add collectors: new block that can pull items from the world or an
inventory on redstone pulse
It can face in all 6 directions unlike the hopper, though it does not
output items and requires a redstone pulse to pull items

Add pipes: a more economical hopper
Pipes are cheaper than hoppers, but only have one slot and can only
output items, not pull items from the world. They also can be placed
facing up if enabled in the config
