Needed label translation for related data

[actionwave34F]

In forms and view we can have related data. The label part does not translates to other languages in
/components/com_fabrik/models/form.php row 4226
We propose this change:
$links[$element->list_id][] = JText::_($label) . ': ' . $referringTable->viewDataLink($popUpLink, $element, null, $linkKey, $val, $count, $f);
