save progress after every guess

Progress was only saved at the start of a game and on Ctrl-C, so a
dropped connection lost every guess made so far. Ctrl-C during the
reveal also saved the scored row without advancing ROW, which gave the
player that guess back on resume.

Save straight after each guess is scored (before the reveal) with the
next row, record the result before the final reveal, and make the
SIGINT trap only tidy up the terminal.
