The idea is that the parse_config method of extension modules can raise either a ConfigError or a JsonValidationError, and it will be magically turned into a legible error message. There's a few components to it: * Separating the "path" and the "message" parts of a ConfigError, so that we can fiddle with the path bit to turn it into an absolute path. * Generally improving the way ConfigErrors get printed. * Passing in the config path to load_module so that it can wrap any exceptions that get caught appropriately.
