Added Urine

First of all, I've searched of the possibilities of usage of urine in everyday life. What I came up with is that; urine 
might be used to charge batteries as it contain acid and small traces of ammonia. although it is not applicable yet in our days so I guessed since the cataclysm set in the future people might figured out how to use urine as a substitute.

So what I've done:

-Added urine. Made it slightly less dangerous than blood and raised the quench factor.
-Added urine as a component in making batteries and plant food.
-Added urine to hospital spawns.
