Update class.rex_sql.inc.php

$sql->hasNext() returns true even if the counter just points to the last row.

[gharlan]

The hasNext function should be used like this:

while ($sql->hasNext()) {
    // ...

    $sql->next();
}

The name is maybe misleading, a better name would be valid(). But the current return value is correct. Otherwise the last row would be skipped.
