- DEPTH decreased from 14 to 12, BACKFILL_DEPTH from 8 to 6, and KO_DEPTH
  from 8 to 6
- new functions for drawing boards for debug output
- symbolic names for colors
- influence function implemented in influence.c and influence.h

- territorial value estimated with influence_delta_territory() instead of
  delta_terri() from moyo module
- influence value estimated with influence module functions instead of
  delta_moyo() from moyo module
- secondary_value weighted down substantially in computation of total move
  value
- symbolic names for printmoyo values
- local optimizations in shapes_callback() to avoid unnecessary reading
- increased depth values when evaluating reading constraints disabled to
  improve speed
- new patterns in conn.db
- local optimization in connections.c, don't evaluate autohelper if there
  is nothing to amalgamate
- autohelper functions xarea, oarea, xmoyo, omoyo, xterri, and oterri
  changed to use functions from influence module
- separate flag to mkpat to decide anchoring policy
- tuning of patterns.db and patterns2.db
