Added warn note to docs about MySQL issues with 0000-00-00 date strings 

MySQL accepts 0000-00-00 as a valid date but MySQLdb converts those
values into None. So there will be problems for instance if trying to
transport the data using dumpdata/loaddata.

This patch refs #6642 that has been closed as wontfix since this is a
particular problem of MySQL.

.. note::

    There are known issues with the way MySQLdb converts date strings into

    datetime objects. Specifically, date strings with value 0000-00-00 are valid for

    MySQL but will be converted into None by MySQLdb.



    This means you should be careful while using loaddata/dumpdata with rows

    that may have 0000-00-00 values, as they will be converted to None.
