PlayerActivity now stores its list state after rotations
added skeleton code that will allow TournamentsActivity to sort chronologically (in addition to reverse chronologically, which is how it works currently)
TournamentsActivity will now sort the list of tournaments
TournamentsActivity will now resume its sort state after rotation
added a condensed version of "Sort Chronologically" and "Sort Reverse Chronologically" to the TournamentsActivity menu
PlayerActivity and TournamentsActivity are now a bit more consistent with each other
