Variant: Add dictionary entry and dictionary specializations.

	* glib/src/varianttype.hg:
	* glib/src/variant_basictypes.h.m4: Renamed the glibmmVariant doxygen
	group to 'Variant'.
	* glib/src/variant.{ccg,hg}: Throw a std::out_of_range exception
	instead of a std::runtime_error one from methods that throw them
	because of indexes being out of bounds.
	(Variant< std::pair<K, V> >): Added this specialization to deal with a
	dictionary entry variant type.
	(Variant< std::map<K, V> >): Added this specialization to deal with
	variant dictionary types.
	(VariantContainerBase::get): Have this method throw a
	std::out_of_range exception if the index is out of range.
	(Variant< std::vector<Glib::ustring> >::get)
	(Variant< std::vector<std::string> >::get): Free the shallow copy of
	the returned string arrays in the get methods of the string variant
	arrays as the docs of the C API say.

	* gio/src/dbusconnection.hg: Added missing _IGNORE()'s.
	* gio/src/dbusproxy.hg: Updated a TODO.
	* examples/dbus/well-known-address-client.cc: Typo.
