[gtk+/gtk-style-context: 88/191] GtkStyleSet: Remove default value for registered properties.

[Carlos Garnacho <carlosg src gnome org>]

commit c7cd9297fb6b3c2a7f1826772b74c315de85e490
Author: Carlos Garnacho <carlosg gnome org>
Date:   Sun Jun 13 17:10:05 2010 +0200

    GtkStyleSet: Remove default value for registered properties.
    
    This should be handled at a higher level, a single default value for all
    states isn't that useful...
