	* app/config/gimpconfig.[ch]: added "gint nest_level" to the
	deserialization functions, so nested calls to deserialize()
	don't error on the trailing ')'. Made the scanner config parse
	one-character identifiers and allow G_CSET_A_2_Z for all
	identifiers.
	Added gimp_config_deserialize_return() because returning the
	correct return value from a deserialize() function is not
	trivial any more with nested calls.

	* app/config/gimpconfig-deserialize.[ch]
	* app/config/gimprc.c
	* app/core/gimpdocumentlist.c
	* app/core/gimpparasitelist.c: use the new return value utility
	function and made the main parsing loops simpler.

	* app/core/gimpunits.c: made the main parsing loops consistent
	with the stuff that uses GimpConfig.

	* app/config/gimpconfig-deserialize.c
	* app/config/gimpconfig-serialize.c: call the
	(de)serialize_property() functions only if the property's class
	implements the method itself (does *not* inherit it from one of
	it's parents).

	* app/core/gimpcontainer.c: implemented deserialization of
	containers. For each child entry encountered in the input, check
	if it's already contained in the container and create it if not.
	If a "gimp" pointer is passed as user_data pass it as construct
	property to g_object_new() when creating the object.

	* app/core/gimpcontext.c: changed deserialization of brush,
	pattern etc. to honor "no_data".

	* app/widgets/gimpdeviceinfo.c: added a "gimp" construct_only
	property which overrides GimpContext's "gimp" property. Moved all
	initialisation code from gimp_device_info_new() to
	gimp_device_info_set_property(PROP_GIMP) so it is properly
	performed if the object is created by GimpContainer's
	deserialize() implementation.

	* app/widgets/gimpdevices.c: made gimp_devices_restore_test() work.
