[Computer-go] replacing dynamic komi with a scoring function

[David Fotland]

Yes.  That's why MCTS prefers the center.  Sometimes the playouts let an
invasion work, so corner territory is not evaluated as being as secure as it
should be.  It seems easier for MCTS to kill groups in the center in the
playouts.
