function entity_translation_translatable_form_submit in Entity Translation 7

Submit handler for the field settings form.

This submit handler maintains consistency between the translatability of an entity and the language under which the field data is stored. When a field is marked as translatable, all the data in $entity->{field_name}[LANGUAGE_NONE] is moved to $entity->{field_name}[$entity_language]. When a field is marked as untranslatable the opposite process occurs. Note that marking a field as untranslatable will cause all of its translations to be permanently removed, with the exception of the one corresponding to the entity language.

  // If a field is untranslatable, it can have no data except under
  // LANGUAGE_NONE. Thus we need a field to be translatable before we convert
  // data to the entity language. Conversely we need to switch data back to
  // LANGUAGE_NONE before making a field untranslatable lest we lose
