[gnugo-devel] Hoshi joseki work

[Evan Berggren Daniel]

- modified joseki regions to solve ninestones:590 (see my previous email)
- responses and continuations for two space high approach
- includes patch from my email 'hoshi joseki fix'

The two space approach josekis are to help with games like
sjfried-gnugo-3.3.17-200303240814.sgf.

Oh, and my mirror of the devel page is available at
http://evand.rh.ncsu.edu/~evand/gnugo/software/gnugo/devel.html if anyone
wants a more up to date version.
