[Florian MÃllner <fmuellner src gnome org>]

commit e2726f3e3862b233a0cb47e22423bf000e540abc
Author: Florian MÃllner <fmuellner gnome org>

    Add a checkbox widget
    
    gnome-keyring dialogs need checkboxes, and while it is possible to
    get pretty close using CSS tricks, a dedicated widgets yields better
    results.
