[gtk+] Move the get_cursor_color in GtkStyleContext

[Paolo Borelli <pborelli src gnome org>]

commit 001697a22a6e094ca37f4f6c230161b08dff5c20
Author: Paolo Borelli <pborelli gnome org>
Date:   Sat Jan 29 12:47:09 2011 +0100

    Move the get_cursor_color in GtkStyleContext
    
    Move the private get_cursor_color method belongs to StyleContext. Change
    the api so that retrieving both primary and secondary color is possible.
    I left the method private for now, though it should probably be public
    as all the other getters.
