Update to XaoS-3.4.

o New Italian translation courtesy of Sergio Zanchetta
o Updated catalog and i18n for German by Andreas Madritsch
o Bug fix to prevent garbled characters when using non-English languages
  on modern systems using UTF-8
o Bug fix to prevent XaoS from crashing after using the Render Animation
  functionality
o Bug fix to prevent incorrect colors on smooth coloring modes with
  certain video modes

XXX: There are also new experimental Aqua and GTK+ frontends, but I didn't
investigate if the GTK+ frontend builds as the release notes claim it's
still buggy.
