[gtk+/wip/matthiasc/caret-color: 1/4] Add the caret-color CSS property

[Matthias Clasen <matthiasc src gnome org>]

commit 8335b89b370b188c15a035b2b10cc1f79827a4b5

    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. Unlike
    CSS, we don't support the weakly defined auto keyword, and just
    use currentColor as the initial value.
