        * glib/glibmm/objectbase.cc:
        * glib/glibmm/objectbase.h: Added connect_property_changed(), 
        as an alternative to use when the property proxies are not 
        available because GLIBMM_PROPERTIES_ENABLED is not defined.
        SignalProxyProperty::connect(): Use notify::propertyname instead of 
        just notify, so do not have to check the property name later. This 
        should be more efficient (when this is used, rarely).
        * glib/glibmm/propertyproxy_base.cc:
        * glib/glibmm/propertyproxy_base.h: Move PropertyProxyConnectionNode
        into the header, so we can reuse it for connect_property_changed().
