Quma

---------------

Released on October 19th 2018

- Make the cursor as first parameter of public custom namespace methods
mandatory. Automatically pass it when the method is called via the
*cur* api.
- Fix ``query.count()``/``len(query)``: Return DBAPI's ``rowcount`` if
available. Don't fetch the result when these methods are called anymore.
Calls of count have overwritten the value of ``rowcount`` and set it
to ``-1``.
