Make this work correctly. While in the past gnuchess may have appeared to

read/parse this book, in reality it wasn't. It doesn't seem to understand
full pgn format and instead uses an abbreviated format (which all the other
book packages use as well). It sort of interprets full pgn but gets lots
of things wrong.

Include a script to convert the book to a proper format and then run gnuchess
across that and it seems to find much less errors.
