[gtk+/wip/csoriano/bookmarks: 25/25] gtkplacesidebar: use GtkListBox



commit a8cc8f30ae27a4a047ee975ae24842334564cbd1
Author: Carlos Soriano <csoriano gnome org>
Date:   Wed May 6 23:07:17 2015 +0200

    gtkplacesidebar: use GtkListBox
    
    We were using GTkTreeView in a simple list. Also, as we know,
    GtkCellRenderers are not the best way to theme and manipulate
    widgets.
    
    So instead use a GtkListBox to modernize the GtkPlacesSidebar,
    and in the way clean up some parts of the code (like headings)
    which were not used anymore.
    Also we don't use a model anymore, since the data is simple
    enough to manage it in a subclass of the row itself.
