Exotherm - Automatic rematch

To make sure changes are actually improving Exotherm's strength, I sometimes have a modified version of the engine play against an older version. I connect both to the FICS as guests, have one challenge the other, and watch to see which version wins more often. To make this a little smoother, I recently added an INI configuration option to have the bot automatically issue a rematch offer after the game ends. That way, the two versions will keep playing each other over and over without my needing to poke them again each time.
