Gob is no longer a requirement for hacking on gnome-games.

[Callum McKenzie <callum spooky-possum org>]

I've just removed any need for gob (an automatic GObject generator) in
the high scores code. So anyone who installed it just to generate the
high scores dialog code can uninstall it now. I assume most people used
the generated files that were also kept in CVS.

The change shouldn't be noticeable, but I suspect the code now leaks a
little memory. This will be fixed soon.
