Gameplay Statistics Reporting

Reports from RaceManager just before a race starts what the player has chosen. It will not report anything identifying but does report:
   * kart
   * track
   * difficulty
   * GP or single race
   * gamemode
   * number of players
   * number of local players
   * number of laps
   * is the track reversed
@samuncle had some pretty valid concerns about how this should be displayed. This implementation was just to get us started and have a simple control for turning stats on and off.
