[gnugo-devel] owl tuning

[Evan Berggren Daniel]

Two new owl patterns, together they solve 13x13:73.  The defense pattern
probably needs a constraint, but I couldn't find one that works (the
commented out one is my best guess).  After the patch, gnugo understands
that the M12 dragon is critical, and finds J8 as the attack move and J7 as
the defense move.

Thanks

Evan Daniel
