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. Submitted by: jkh
