Support printing of piece command specified in ini file

Lines behind the game definition starting with # (after an empty
such line) are sent to the GUI with a 'piece' prefix. This allows
Fairy-Max to implement the new XBoard protocol for communicating
piece moves to the GUI, so the latter can do legality testing and
better SAN generation.
