print/scribus-devel: update 1.5.8 → 1.6.2 (copy of print/scribus)

• 1.5.8 is outdated development version, older than the stable version;
• the port is almost broken (silent grab, incorrect dependency list);
• the next development branch 1.7 has no releases yet;
• keep the port for upcoming releases from the 1.7 branch.
