Stop with the exclusive reward store traits!!!!

I think this trait works better as a reward trait. We have carefree reward trait that takes care of all tense moodlets. Makes sense that a trait taking care of fear moodlets would also be a reward trait. You can treat it as a reward to get rid of the negative moodlets or you can buy it to enhance your sims personality a little. If it was a CAS trait it would be more limited as older sims coudn't gain it anymore.
