Assert that values are not equal to certain values with NOT

[GoogleCodeExporter]

A natural counterpart to the ANY helper is the NOT helper, which would allow 
you to assert that an argument or value is anything except some certain value. 
Example:

    >>> mock = Mock(return_value=None)
    >>> mock('foo')
    >>> mock.assert_called_once_with(NOT('bar', 'baz', 'qux'))

Attached is a patch for NOT with tests and mediocre documentation. Let me know 
if any more changes are needed. :D
