Add dialog.tpl support to price option label

In option.tpl add support for the Dialog.tpl to support quick editing of multiple languages for the label.

Sadly just adding

{include file='CRM/Core/I18n/Dialog.tpl' table='civicrm_price_field_value' field='label' id=$id}

doesn't do it, as it can't find the $id (which I find odd....). Maybe I need to prepare something in option.php so it can find the $id in option.tpl? I tested and with a "id=6" instead of "id=$id" it works like a charm. So the issue is to get the id replaced correctly.
