Jordan K. Hubbard 554eb505f8 Bring in the 4.4 Lite games directory, modulo man page changes and segregation
of the x11 based games.  I'm not going to tag the originals with bsd_44_lite
and do this in two stages since it's just not worth it for this collection,
and I've got directory renames to deal with that way.  Bleah.

* Some numerical conventions:

* Numeric values which are one color or the other use
* -1 for white, 1 for red.
* Hence, white will be negative values, red positive one.
* This makes a lot of sense since white is going in decending
* order around the board, and red is ascending.
