[gnome-software/gnome-3-10] Do not use the application state to modify how widgets are drawn

[Richard Hughes <rhughes src gnome org>]

commit 27be2f7861830653abf17eb5fdf85792fdac00a0

    Do not use the application state to modify how widgets are drawn
    
    It's not nice to change the way the widget works using a special state value.
    Instead of this, provide a method that only the updates panel will use and make
    things less magic.
