[Florian Müllner <fmuellner src gnome org>]

commit 2f0039e7dd11e86ecd4c66ee9ca52d05fa3fe296
Author: Florian Müllner <fmuellner gnome org>
Date:   Wed Jul 6 19:56:47 2016 +0200

    app: Add a construct-only app-info property
    
    This will allow us to create a ShellApp from JS code, for instance
    for .desktop files that aren't known to the AppSystem.
