* Merge from Debian unstable, remaining Ubuntu changes: - debian/patches: + xubuntu_migrate-tasklist-separator.patch: added, try to be smart and work around the non-expandable tasklist plugin from 4.10 by setting as expandable the separator next to it (should work with the default panel layouts from Xubuntu, Mythbuntu and UbuntuStudio). + xubuntu_add-calendar-popup-to-clock-plugin.patch: added, taken from upstream git to show a calendar when left-clicking on the clock plugin (so we don't need orage/xfce4-datetime-plugin for this feature only).
