* DB_Connection_Installer resembles adodb_db_connection but is created with already connected db connection instead of DSN. It's purpose is to fake "normal" db connection in order module instalators to be able to use *_DBC when installing/uninstalling
* @param string $sequence_name Name of the sequence that will be used (for MySQL where sequences are not available - name of the db table that fakes the sequence)
* @param integer $start Starting value of the sequence (will be used only if sequence does not exist yet, i.e. for initialization)
* @return integer Generated ID
