[gnugo-devel] owl tuning patch

[Gunnar Farneback]

This is a pure owl tuning patch, where all new patterns use the
owl_strong_dragon() autohelper to find moves connecting out to a
supposedly strong neighbor. Regression delta:

arb:210         PASS D8 [D8]
global:34       PASS N6 [N6]
owl1:294        PASS 1 M9 [1 M9]
nando:24        PASS 1 M13 [1 M13]

The owl node count for the full regressions is reduced by 1.2%.
Reading and connection nodes vary less than 0.1%.
