Here are the changes for the documentation; I also changed the values
of joseki moves which were not up to date with shapes.c.
Btw, why was the shape bonus for J moves dropped? I saw GNU Go depart
from the proper joseki a couple of times, and the shape bonus might
have prevented this.

One prefers not to use this approach but in practice it is
