gnome-games 2.5.1

[Callum McKenzie <callum physics otago ac nz>]

I've just made a belated release of gnome-games 2.5.1. It now passes
every build test I can throw at it (now is a good time to look up
"hubris" in the dictionary). You can find it at:

http://ftp.gnome.org/pub/GNOME/sources/gnome-games/2.5/

There has been some significant reworking of the build system. The
freecell mode of aisleriot now supports supermove and there has been
some superficial UI work done on gnometris and gnomine.
