getting a game with marked stones now show correctly the territories, but if refusing, marking new stones only toggles the previously marked stones in the server
score2 is a problem to estimate the score because the previous marked stones are kept on the server
refuse now works pretty well by computing which stones to toggle
bugfix init server
TODO: in SCORE2 too much server commands sent auto one after the other; failure of one of them is a problem. TODO: separate each command with its own button
