[gtk+] Make GtkHSV use GtkStyleContext

[Carlos Garnacho <carlosg src gnome org>]

commit 2f6514ce3415f42690180e09dd35054a16f57d2c

    Make GtkHSV use GtkStyleContext
    
    two custom classes replace the light/dark focus detail strings,
    it doesn't make much sense to have a GTK_STYLE_CLASS_* for that.
