[Dolibarr-user] Can't have more than 10 bills a months

[Brice Delmotte]

There seems to be a problem in the file lune.modules.php of the  
includes/modules/facture/lune folder
It takes only the last number of the bill reference number :
      $sql = "SELECT max(0+substring(facnumber, 8)) FROM  
".MAIN_DB_PREFIX."facture";
      $sql .= " WHERE facnumber like '$prefix".$date."%'";
So I changed it in :
      $sql = "SELECT max(0+substring(facnumber,6,8)) FROM  
".MAIN_DB_PREFIX."facture";
      $sql .= " WHERE facnumber like '$prefix".$date."%'";
