I was getting sick of seeing the *-i18n packages completely blow away anything else useful out of the recent updates sidebar. Revamp the logic here again to do something about it. As we did before, grab packages from the database and attempt to group them, but this time do it by only repo and pkgbase. From there, if we have packages in the group with a pkgname matching pkgbase, we will link just those. If not, we will create some stub objects that link to our relatively new virtual package overview screen. Signed-off-by: Dan McGee <dan@archlinux.org>
