[Draft] PrestaShop Multi connection

<?php

/** [Draft] PrestaShop Multi connection
* Put this file in the /override/classes directory
*
* If we need to use a different database with different username (or host),
* This class allows to make a second mysql connection (and more if you need).
*
*
* Usage :
* $db1 = new MySQL2(_DB_SERVER_, _DB_USER_, _DB_PASSWD_, 'dbname1', true);
* $db2 = new MySQL2('1.2.3.4', 'un_utilisateur', 'un_mot_de_passe', 'le_nom_de_la_bdd', true);
*
* Notice : Strict Standards php warning can appear because __construct
* and connect methods have an extra parameter
