No form_of tags for some Latin inflections

[Vuizur]

Some latin words currently don't have the form_of tag, probably because they contain a string like "indicative/imperative" or "present/perfect" in the grammar specification. An example word would be putrefitis. More examples can be found this dictionary here, one only has to search for grammar terms like "plural" or "singular". (All forms with form_of tags should have been filtered out before.)
