[gtk+/wip/matthiasc/caret-color: 2/4] Add the caret-color CSS property

[Matthias Clasen <matthiasc src gnome org>]

commit 0903bca8aa55b43e44825dcde7e5aec40f9aac88
Author: Matthias Clasen <mclasen redhat com>

    Add the caret-color CSS property
    
    This property is defined in http://www.w3.org/TR/css3-ui/#caret-color.
    We also add a -gtk-secondary-caret-color property, since GTK+ has
    supported differently colored split cursors in the past.
