randomize some guests stats

[Die4Ever]

adjusting how easy it is for guests to become unhappy would be good, but it would require some difficult logic in manually manipulating their current happiness variable?

minIntensity and maxIntensity could also be randomized per guest, but is that better than doing it globally?

random chance for guests needing to use the bathroom often would be funny

interface Guest extends Peep {
        /**
         * How happy the guest is between 0 and 255.

        happiness: number;

        /**

        happinessTarget: number;

        /**
