	* app/config/gimpconfig-params.h: made object properties
	G_PARAM_READWRITE by default. Added flag GIMP_PARAM_AGGREGATE
	which indicates that an object property is not a reference but a
	real part of its owner.

	* app/config/gimpconfig-deserialize.c: g_object_set_property()
	object properties only if they are not GIMP_PARAM_AGGREGATE.

	* app/config/gimpconfig-utils.c (gimp_config_copy_properties,
	gimp_config_reset_properties): copy and reset GIMP_PARAM_AGGREGATE
	object properties correctly.

	* app/config/gimpconfig-serialize.c: don't call
	gimp_config_writer_open/close() for properties which are handled
	by a GimpConfigIface::serialize_property() implementation.

	* app/core/gimpcontext.c: removed exlicit G_PARAM_WRITABLE from
	object properties since that's the default now. Call
	gimp_config_writer_open/close() when serializing properties.

	* app/core/gimpviewable.c (gimp_viewable_get_property): use
	gimp_viewable_get_stock_id().
	(gimp_viewable_set_stock_id): set stock_id to NULL if the new
	stock_id is the same as viewable_class->default_stock_id.
	Added serialize_property() which skips stock_id serialization
	if it is NULL.

	* app/tools/gimptextoptions.c: made the "text" property
	GIMP_PARAM_AGGREGATE. Added gimp_text_options_set_property()
	(which does nothing).

	* app/widgets/gimptemplateeditor.[ch]: added an optional
	GimpViewableButton to change the template's icon.

	* app/gui/file-new-dialog.c: create it with the icon button so it
	gets some testing.
