[racket] Book parts in scribble

I've added a 'grouper style property for parts, which makes a part like
like a "part" in the sense of a book.

 #lang scribble/base

 @title{The Book}

 @section[#:style 'grouper]{First part}
 @subsection{First chapter}
 @subsection{Second chapter}

 @section[#:style 'grouper]{Second part}
 @subsection{Third chapter}
 @subsection{Fourth chapter}

I've also added a 'hidden-number style property, which I think is what
Matthias needs for intermezzos.

Finally, there are now `scribble/book' and `scribble/report' languages,
which are like `scribble/base' but set up Latex to use the standard
"book" or "report" format. Most of the Latex configuration is
redirecting section commands to chapter commands, etc.
