+	* gstreamer/gstreamermm/value_base_type_traits.h:
+	* gstreamer/src/propertyprobe.hg: Defined a template specialization of
+	glibmm's Glib::Container_Helpers::TypeTraits<> so that
+	Glib::ArrayHandle<> can be used to wrap a GlibValueArray.  Wrapped
+	Gst::ProperyProbe::get_values() which returns a
+	Glib::ArrayHandle<Glib::ValueBase>.
+	* configure.ac:
+	* gstreamer/src/Makefile_list_of_hg.am_fragment: Added playbin
+	plug-in.
+	* gstreamer/src/mixer.hg: GstMixer signals are not available to
+	gen_defs_gst tool and have been deprecated so marked the TODO to wrap
+	them complete.
