Jms multisite for joomla version 1.2.85

• Added the possibility automatically generate a site title.
• Revamp the dynamic DB creation and dynamic user creation to remove all the access to Joomla in aim to avoid compatibility issue consecutive to ascending compatibility not provided by Joomla.
  Implemented a new light DB API that is used to create the DB and the users.
  This solve the problem present in Joomla 1.6 or higher that provide copy of the DB connection instead of a reference and that result issue in DB object to get informed of operation performed by other DB object.
  The new API create unique instance and not more copy of instance like in Joomla 1.6 or higher.
