Allow adjectives to become 'nominal predicates'.

       This small change allows adjectives to become nominal
       predicates directly. This distinguishes two different
       interpretations of a word like 'mavi(dir)' one being direct
       Adj->V: `it is blue', the other Adj->N->V: `it is the blue
       one'. The other adjectivals (numbers, determiners) are still
       not allowed to become a verb by zero-derivation.
