Fixed an issue where NearestStopsFragment would attempt to initiate a load, even when the Fragment is detached from the FragmentManager. Fixed an issue where the user has selected from the contextual menu in DisplayBusStopDataFragment but the index it obtains is invalid. Attempted to fix memory issue with the star button by using the proper methods to set the image, rather than setting it as a background image resource.
