contrib/paclist: rewrite in bash
The original concept for this script was a bash implementation, but turned out to be unreasonable at the time due to the efficiencies of the database format. Since those have been resolved, we can rewrite this in bash as a much simpler script. All the action happens in a single line, but we add extend this a little, binding to gettext to keep our pacman translations intact.
