[Framers] Total Page Count Variable

[Robert Lauriston]

For the last ten years or so, since computers have had enough memory /
horsepower that it isn't a problem, I put all the chapters in a single
.fm file. Then you don't have to worry about someone adding a file to
the end and screwing up the unfortunate kludge required because Adobe
never added the book-level variables users have asked for repeatedly.
