(Por) change mk2A paradigm

(such that the second argument is the adverb string, not the feminine
form, which is easier to predict)
- fix bug in adjVo paradigm
- add two cases to mkAdjReg smart paradigm
- update lexicon

tbh, it is much more common to need to correct the adverbial form
because it doesn't have the accents that the adjectival forms may
have, so if there's a way of removing accents easily, that might be
better.
