Allow UDP download from paks that are not numbered.

Browse source 
Until now the UDP download code prohibited downloading of maps from all
pak files. That was some kind of copy protection, without the limitation
demo users could download assets from the full version. Don't apply that
protection for all paks, but only for numbered .pak files.

This could be enhanced by limiting the protection to pak0 to pak2 for
baseq2 and pak0 for both xatrix and rogue.
