Update deskutils/xfce4-notes to 0.9.6.
Please note that the upstream package name has changed from
xfce4-notes to xfce4-notes-plugin, which is in line with
several other panel plugins for xfce4. I have renamed the
package accordingly. Maybe it would make sense to repo-copy
the port to keep naming in sync?
