Give the nitwit villagers a use other than breeding.

Nitwit villagers should be able to give the player more things to do. This is why I propose that the nitwit villagers can give minor quests such as "Kill 5 zombies at night to defend the village." or "replant the crops in the crop bed." And of course, the nitwits would give rewards from bread to emeralds. I think this would help give villagers more use in the game other than farming.
