Use inline-toolbar style for the toolbar containing buttons for controlling jobs. Set junctions so it visually connects with the list of jobs. https://bugzilla.gnome.org/show_bug.cgi?id=690421
This commit places list of jobs to separate dialog. The dialog is updated through calling of pp_jobs_dialog_update() from "Printers" panel because the panel is already subscribed to cups notifications.
