gnuchess added

[Chris Ricker <kaboom oobleck net>]

I've imported an SRPM for GNU chess based on the last one in the Fedora 
Core development CVS. Technically no approval's needed since it was in FC 
3, but I'll wait a couple of days to build it in case anyone wants to 
review the changes I made....

Once that's in I'll add xboard as well if no one else wants to maintain it

later,
