[gtk+/wip/matthiasc/caret-color: 2/4] Use the caret-color properties for drawing carets

[Matthias Clasen <matthiasc src gnome org>]

commit 97bfc84649fbe2233e72bc56d91f1ad81c924195

    Use the caret-color properties for drawing carets
    
    Replace the cursor-color and secondary-cursor-color style
    properties with the caret-color and -gtk-secondary-caret-color
    CSS properties.
    
    For the 'auto' value of these properties, we keep the same
    behavior that we used to have when the style properties are
    not explicitly set.
