Probability fixes: 1) Game now resets the overall probability in between runs.  Previously, it was considering the probability that the play AND THE PLAY BEFORE IT worked.  This is via the resetProbability() functions in Game and Play.  2) Variability no longer produces negative or >1 results.  This is fixed by dampening the variability and changing the variability function in the player class so that it won't allow the probability of any one event to be <0 or >1 (because... rules of probability).
