[glib/wip/gproperty-2: 24/25] gobject: Initialize GProperties at instance init time



commit 75149e432d045069c238edba2e65d35f285fb018
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Tue Jun 11 14:01:04 2013 +0100

    gobject: Initialize GProperties at instance init time
    
    Using their default value. This removes the need to manually calling
    g_property_init_default(), which means we can make it private.
