[EM] using welfare functions in election methods

Ooo, I like it. Now I want to re-run all my old simulations that just 
measured average happiness.

Though, the tricky thing I've always run into when trying to formulate a 
better social utility measure is that when trying to make sure no one is 
left too far behind, do we unfairly reward people who complain too much?
