[gdm/gnome-2-30] Drop user properties in favor of a "changed" signal

[William Jon McCann <mccann src gnome org>]

commit f5742b27d6921858e27d53a07c11793c34423b9a
Author: Ray Strode <rstrode redhat com>
Date:   Mon Mar 15 14:21:56 2010 -0400

    Drop user properties in favor of a "changed" signal
    
    This is less specific, but good enough, and will make
    changing out the backend easier.
