This modifies the NotificationCenter class to do the following: - add an ivar to the class for an array to hold observers that need to be released when they are removed - adds an observer to that array if the observer is of class GSNotificationObserver - upon removing an observer, check if it is in that array, if so remove it from the array and release it. This replaces the previous implementation which checked the class of the observer as it was being removed, which would cause a crash if the observer had been deallocated.
