lib/src/*/Numeral*.gf: fix inconsistent inheritance form Cat

While the abstract Numeral inherits only Cat[Numeral,Digits], some of the
concrete NumeralNNN of Numeral inherited everything from CatNNN.

Normally the compiler outputs a warning message when a concrete syntax 
contains superflous lincats, but apparently not when they get included
through inheritance...

This does not seem to cause problems in the Haskell run-time system, but the 
C run-time system fails to load PGFs with superflous lincats.

This problems shows up when creating application grammars that inherit Numeral.
The Phrasebook is an example of such a grammar.
