Done phase

A game is expected to change its state to DONE when the game is over. In most cases, a winner (or tie game) will be determined. The game results, including winner, score and the like, can be reported back to ggzd via the GAME_REPORT message. If a game log or savegame has been kept, the filename of it can be reported as well for further reference, using a SAVEGAME_REPORT message.
