[gtk+/gtk-2-18] Use a url label instead of a link button

[Matthias Clasen <matthiasc src gnome org>]

commit 42b5eb624639933c442efe4295b1870c4234bae4
Author: Matthias Clasen <mclasen redhat com>

    Use a url label instead of a link button
    
    This looks nicer, and allows us to make the url-hook work again
    for the website url. Fixes bug 603201.
    (cherry picked from commit 478ca88ae5393c422f7c72795d7dd0df29108511)
