function _webform_localization_mollom_form_alter in Webform Localization 7.4

Interaction with mollom_form_alter() for 'single_webform' localization.

If the translation source node's webform is protected by mollom, and uses our 'single_webform' setting, then we must also protect the other nodes in the translation set.

This is because each node in the translation set will still have a unique client form_id (based on the nid, not the tnid), but mollom will only know about one of those form_ids.
