[gnugo-devel] fixed_anchor attribute added to pattern database

[Trevor Morris]

http://www.public32.com/games/go/trevor_3_12.2

 - Added -a parameter to mkpat
 - Use fixed_anchor to default anchor_in_goal in matchpat
 - Make check_pattern_light a bit lighter if anchor_in_goal

This has no effects unless the "-a" parameter is added to the
owl_attackpats.db  mkpat command line.

The performance delta, on the full regression set, is:
  with -a on owl_attackpats.db:  208 minutes
  with -m on owl_attackpats.db: 215 minutes.

This 3%+ performance increase seems real, since I ran the first
set while doing other stuff and the second ran over night.

I've not evaluated these failures, but plan to do that shortly.  Meanwhile
this can be added to CVS, since it causes no change by default.

Here's the unexpected results using -a (13 PASSED, 24 FAILED):
