Bug#512456: XQF should be suggested

[FTF 3k3]

Package: nexuiz
Version: 2.4.2-1

I might be wrong, but I don't think most users needs XQF coming with
Nexuiz. This isn't unusual to use Nexuiz without XQF since a server
browser is already included in the game.

Debian Policy Manual (Chapter 7) :
"The Recommends field should list packages that would be found together
with this one in all but unusual installations."

Maybe it would be better to suggest XQF's package.

Regards.
