* Remove setuptools requirement, reverted to pure distutils
* use_decimal default for encoding (dump, dumps, JSONEncoder) is now True

tuple_as_array=False option.

* namedtuple (or other tuple subclasses with _asdict methods) are now
encoded as JSON objects rather than arrays by default. Can be disabled
