[evince/hildon-2-28] shell: [maemo5] Add custom gtkrc file to redefine stock icons

[Christian Persch <chpe src gnome org>]

commit 8370d228c6b623c8ea7c1f9788580ff0b82ba875

    shell: [maemo5] Add custom gtkrc file to redefine stock icons
    
    On maemo5, the stock icons aren't available in the toolbar size used, which
    makes them blurry due to scaling. Add a custom gtkrc file to re-define
    the stock icons using the platform icons that are available in the
    required size.
    
    Analogous to bug #584669.
