Modified the mysql.py module to alter the behavior when 0 rows are returned.  This is because some SELECT statements might return 0 rows and the difference in returned verbiage is problematic.  We alter the code so that if the query is a SELECT, we always describe the results as 'rows returned'.  If the query does not start with that, then we use 'rows affected'
