[gnome-software] Add a confirmation dialog for updates

[Matthias Clasen <matthiasc src gnome org>]

commit 769e88283c72e0fe60edf50fdfdec7817c4781dc
Author: Matthias Clasen <mclasen redhat com>
Date:   Thu Aug 22 15:57:24 2013 -0400

    Add a confirmation dialog for updates
    
    This is temporary until we have a shell modal dialog, and
    can also be used as fallback when not running under the shell.
    We're not triggering any offline update yet.
