* Replace datetime by clock now that it features a calendar as well. * Switch gtk-greeter to Greybird+elementary-xfce until the fate of Greybird-lightdm is decided. * usr/share/xubuntu/applications/xfhelp4.desktop: fixed to use exo-open instead of xfbrowser4 (was part of xfce4-utils, obsolete with 4.10). * etc/xdg/xdg-xubuntu/menus/xfce-applications.menu: updated settings items to ignore with Xfce 4.10.
