Extend translation ignore list for metadata values in vocabulary

Added most notably `portal_type`, `review_state` and `Subject` but also `exclude_from_nav`, `is_folderish`, `last_comment_date`, `meta_type` and `total_comments` to ``BaseVocabularyView`` ``translate_ignored`` list.
Some of them are necessary for frontend logic and others cannot be translated.
Fixes #77
