fonts, YACC cross-reference

[Logical Language Group <lojbab@ACCESS.DIGEX.NET>]

The SIL IPA fonts, needed for viewing Chapter 3 correctly, are
now available at ftp:/ftp.access.digex.net/pub/lojbab/silip12a.zip .
Both TrueType and Postscript Type 1 versions are available in the archive.

I have added a YACC Cross-Reference to Chapter 21, supplementing the
EBNF Cross-Reference already present.  This is not a substantive
change.

Bob and Bob, this is your "GO" notification.
