asks the user to enter a name for the "player". The player’s name must not be blank. If this option is chosen again after a player has already been set up, a "new" player is created (ie. with a new name, no prizes, $0 spent). Note that the "new" player replaces the "old" player - ie. there is only ever one player at any one time.
