Villager tasks and job animations

First of all I think that you should be able to do tasks for villagers to earn emeralds. For example, a task for a shepherd might be: shear sheep. Then each sheep you shear would earn you one emerald. Secondly, I think the villagers should have an animation of them doing their job. The fisherman might be fishing, the armorer crafting armour on an anvil, and a leather worker/cleric dipping materials in a cauldron.
