(gomoku-mode-map): Added numeric keypad for 8 directions, changed
comments to lowercase (C-c rather than C-C), added SPC to play and
undo's binding to go back.
(gomoku-emacs-won, gomoku-font-lock-O-face, gomoku-font-lock-X-face)
(gomoku-font-lock-keywords):  New variables.
(gomoku-mode): Use it and make buffer read-only for user.
(gomoku-terminate-game): Remove (ding) -- maybe should be optonal.
(gomoku-init-display): Rewritten, makes fields intangible so you
can't go in between.  Make free fields have mouse-face.
(gomoku-cross-qtuple): Take account of intangible text, and that
empty lines are now really empty.
(gomoku-move-left, gomoku-move-right): Removed thanks to intangibility.
(gomoku-move-ne, -se, -nw, -sw): Use normal left / right motion.
