Supply charset utf-8 for mysql connection

Supply charset argument for connection creation for mysql, even for
python2: The parameter was conditional on python version > 2 but seems
to work fine with python2.7. According to the MySQLdb API docs, the
charset argument is supported with MySQL 4.1 which was released in 2004.
