Doors Closed

# Doors closed Makes villagers close doors more aggressively. In vanilla, villagers are already supposed to close doors they have opened, but ocasionally, they fail to do so. They also _never_ close a door that was already open. Without player intervention, a village will tend toward a state of having all doors open at all time. Not great for safety. ## Changes - Villagers who find an open door will now close it after walking through. - Fixes a bug that causes villagers to, on rare occasions, not close a door they walked through, even if it was already closed when they found it.
