[gnugo-devel] tuning

[Evan Berggren Daniel]

A couple new owl patterns, 2 test revisions, and a new testcase (solved by
the patterns).

The regression delta:

strategy2:77    FAIL
trevor:740      PASS
trevorc:240     PASS
nngs4:340       FAIL
ninestones:370  PASS

In strategy2:77, the stone at H17 is now considered critical, and gnugo
plays H15 as black to kill it.  This is probably an improvement over the
current reading of the stone as unconditionally alive.

nngs4:340 looks accidental, though I haven't investigated.

The three PASSes are real.
