Basically ``.post('foo', 'bar', 'baz')`` will POST http://www.reddit.com/foo/bar/baz/.json.  ``kwargs`` supplied will be passed to ``requests.post`` after having ``modhash`` and ``cookies`` injected, and after having modhash injected into ``kwargs['data']`` if logged in.  Injection only occurs if they don't already exist.
