Language order

probably you have solved it yourself, but in case somebody else needs a solution, this can be useful:
in the /module/blocklanguages/blocklanguages.php file put

function cmp($a, $b)
{
  //language iso_code in the desired order:
  $new_order = array("fr", "es", "en", "de");
  foreach($new_order as &$value)
  {
    if ($a["iso_code"]==$value) return -1;
    if ($b["iso_code"]==$value) return 1; 
  }
}

Paste this code:

usort($languages,"cmp");

$smarty->assign('languages', $languages);
