I propose to change __ne__ of `object` in the following form:

	class NewObject(object):
		def __ne__(self, other):
			return not self.__eq__(other)

Currently overwriting the `__eq__` method requires also overwriting `__ne__`. In a vast majority of cases this results in some boilerplate code as:

    (a == b) ^ (a != b) == True

to reduce surprises. Changing the default behavior still allows for the limited number of use cases where we want to implement __ne__ differently.


In short I propose the same behavior than __str__ and __repr__ have for __eq__ and __ne__.
