[gnome-maps/wip/notifications: 3/4] Add in app notifications

[Mattias Bengtsson <mattiasb src gnome org>]

commit 42445ec19225ccfaf96ef744da1cfff9d51ad003
Author: Mattias Bengtsson <mattias jc bengtsson gmail com>
Date:   Wed Feb 5 19:26:24 2014 +0100

    Add in app notifications
    
    This patch adds in app notifications. The code is derived from
    gtk-widget-factory.
    The Notification widget inherits from GtkRevealer and has a
    showNotification()- and a dismiss() method.
