def hig_category_vbox(title, spacing=6):

    spacing  the space to put between children. HIG say is should be 6, but
    while packing Gtk.LinkButtons there is too much space between the links
    when packing with 6 pixels. So I added the spacing parameter.
    Return a tuple of two boxes:
    box1 -- a box containing everything including the title. Useful
            if you have to hide a category.
    box2    The box you should pack your stuff in.
