The Jms Multisite for joomla version 1.3.01  fix some Joomla 3.0 compatibility issues:

• Fix the selection of a JMS template to allow action such as "new like" or "delete".
• Fix the save of a new slave site "configuration.php" parameters. (fix the setValue() function that is removed in j3.0).
• Fix the "check for update" to replace the call to getValue() function that is no more present in j3.0 and also use a zip file instead of "tar.gz".
