Add an 'active' property to ShellButtonBox. This allows ShellButtonBox to be used as a "toggle button". It's up the application to connect it to the ::activate signal; there's no default handling of this. (It's seldom that the only time you want to toggle a toggle button through the user interface, so you need some connection to the backend data store in any case. Removing the default handling all-together prevents weird interactions.) When we have built-in styling for ShellButtonBox the 'active' state would be one of the elements that would be affect the styling. http://bugzilla.gnome.org/show_bug.cgi?id=593502
