- owl tuning

Mostly corrects FAILS with owl_attackpats when using "-a".

A few things to note:
 - "-a" option doesn't work with patch trevor_3_12.3a, because the number of
DFA states bloats to over 65k.  None-the-less, please put both these patches
in, and I'll patch over 3a with another patch that implements offset values in
the DFA, which is easy with 65k steps to work with.  I've been unable to
get below about 2000, though, so using 8 bits isn't going to be easy.

- Currently the goal does not include stones added during the owl reading.
These should probably be added with a distinct non-zero value, so these
new stones can be anchors but won't break existing owl assumptions about
the goal.  Namely, if all goal stones are captured, it's the dragon's considered

 - The anchor is important in the symmetries.  Pretty obvious, but easy to
miss.  Of course, it has no effect in the current CVS.

Even without "-a", get the following improvement:
  owl_rot:125: PASSED
