Villager treatment

Villagers being put in a 2 block tall box that doesn't allow them to move isn't a very good mechanic, I suggest that villagers should increase their trades when they are unable to sleep and don't have much space to walk around, And perhaps stuff like iron golems, extra space, room to talk with other villagers, and farmland can decrease prices, This would be calculated by a "Happiness" value that goes up and down based on the villager's living situation, This would help balance villagers and encourage players to make actual villages instead of locking them in small boxes
