Handicap games need special gtp commands

See original GitHub issue

Hi, Following up on https://github.com/pasky/pachi/issues/82, it seems sabaki is sending handicap stones as play b commands instead of using dedicated gtp commands, so engines are mislead into thinking it’s an even game. Pachi resigns high handicap games when playing through sabaki right now because of this.

For chinese rules set_free_handicap / place_free_handicap command should be used to send/get handicap stones. Or just fixed_handicap with japanese rules.

gtp2ogs had the same issue some time ago, could check https://github.com/online-go/gtp2ogs/issues/65 for details.
