[ekiga/ds-gtk-application] GtkInfoBar: Added Gm version of a GtkInfoBar.

[Damien Sandras <dsandras src gnome org>]

commit 17826d921fc8ad70c5c48421083663cd87f34b19
Author: Damien Sandras <dsandras seconix com>
Date:   Thu Nov 6 19:48:32 2014 +0100

    GtkInfoBar: Added Gm version of a GtkInfoBar.
    
    It is a convenience GObject so that "Information" messages are displayed
    for a few seconds, then are automatically hidden. Other message types
    have an explicit close action.
