* Merge to Debian; remaining Ubuntu changes:
  - debian/rules: Ignore libgnome-mount for dh_shlibdeps, so that
    gnome-mount does not end up depending on half of Gnome just for the
    nautilus extension. This keeps it suitable for XFCE.
  - debian/control: Add dependency to policykit-gnome.

    + 01_missing_include.patch
