Subject: [PATCH 1/1] Fix recently-used tracking for DBusActivatable apps

For DBusActivatable apps GLib uses D-Bus activation internally and
never calls notify_desktop_launch(), so zeitgeist-datahub does not
receive the org.gtk.gio.DesktopAppInfo.Launched signal and the app
does not appear in recently-used. Send the signal manually.
