- Add docstring
- Check arguments
- Rename 'sessionkey' to 'filekey'. Since the existing implementation
  was broken ('sessionkey' was sent to the server as 'session_key'),
  it is expected that this rename will not break any existing tools.

Conflicts:
	mwclient/client.py

Null edits won't include 'newtimestamp' in the response

- Note the following exception replacements:
  mwclient.errors.HTTPError -> requests.exceptions.ConnectionError
  mwclient.errors.HTTPStatusError -> requests.exceptions.HTTPError
  mwclient.errors.HTTPRedirectError -> requests.exceptions.TooManyRedirects

- Removed the `compability.old_upload` method, which was used for
  MediaWiki < 1.16.

- Requests automatically decompresses gzip-encoded responses, and
  does its best to decode response content to unicode when possible.

- [#53] Using the Responses library to mock http requests in tests

- Keep automated tests to be run with py.test in './tests/'
  and examples in './examples/'
- Rename test to adhere to 'Conventions for Python test discovery'
  (http://pytest.org/latest/goodpractises.html#test-discovery)

Add support for the properties 'rights', 'witheditsonly' and
'activeusers'. Adding all arguments to the end of the argument
list to avoid breaking any existing clients depending on the
existing argument order.
