* clutter/json/json-parser.c:
	(json_scanner_msg_handler): Set the GError to be returned by
	the parsing functions into the GScanner error message handler.

	(json_parser_object): Return the symbol token in case we have
	a parse error after the member name.

	(json_parser_load_from_data): Propagate the error set in the
	message handler, if any.

	* clutter/json/json-node.c (json_node_free): Unref the objects
	only if are set, to avoid a couple of needless criticals we
	get on error.

	* tests/test-script.json: More properties.
