* Flat diff import upstream git commits since 4.12.97 from KDE/4.13 branch in patches/upstream_git.patch (using flat diff because of intermediate merges) * Bring back kubuntu_disable-gpg-backend.diff dropped in 4:4.12.97-0ubuntu2 in a revised, more complete version. In addition to changes brought in by upstream_git.patch this should make the disabling work as intended.
