Subject: [PATCH] GladeGtkBox: fix glade_gtk_box_post_create
Some widgets with contruct properties like GtkMessageDialog get
rebuilt right after they are created on project loading so we need
to check glade_project_is_loading() intead of GLADE_CREATE_LOAD
and use the object ad the connect data to make sure it gets disconected
if it was the object being rebuilt
