[gtk+/places-sidebar] New signal populate-popup

[Federico Mena Quintero <federico src gnome org>]

commit e00498fcd8d5a006c0016bce6e2f77e5c78cfc82
Author: Federico Mena Quintero <federico gnome org>
Date:   Fri Dec 14 11:57:49 2012 -0600

    New signal populate-popup
    
    Instead of conditionally creating contextual menu items like 'Show file properties',
    we'll instead let the caller populate the popup menu, as is done for GtkEntry.
