[gnugo-devel] hoshi patch

[Evan Berggren Daniel]

- alternate continuations after one space low pincer

After an opponent makes the keima approach, and gnugo plays the one space
low pincer, if opponent jumps and then invades at 3,3, gnugo will block on
the wrong side.  This marks the correct block as joseki.  It also adds
another continuation for the pincered player.
