Return "" for unwritten symbols in Symbol.config_string
The previous return value was None. Returning "" makes write_config() neater and feels a bit more Pythonic. It might simplify the implementation of some planned features as well. This is a small API break, so the major version will be bumped to 4 in the next release. Only code that explicitly tests Symbol.config_string against None will be affected: 'if sym.config_string is None:' will break, but not 'if not sym.config_string:'.
