Title: Provided a way to spawn a green robed villager.

The entity type villager had no way of spawning a green-robed villager. A user on the bukkit forums wished to spawn a green-robed villager, but there was no way. This provides a way, however, the profession type is just VILLAGER, because green-robed villagers have no named profession on the wiki.
