Title: Pdomysql

Now that the stuff in JDatabaseMysql is no longer needed it makes sense to implement a PDO-MySQL based driver since according to http://php.net/manual/en/function.mysql-connect.php use of the MySQL extensions is discouraged. This pull request replaces the old Mysql driver with a PDO based driver and makes it possible to use prepared statements with MySQL.
