[PATCH] svnbook revision number, take #2 (was Re: doc/book request)

This time with a proper (I think?) log message, incorporating feedback
from other list members. Tested with HTML, partially tested with
PostScript.

Bruce.

Log:

Automatically include a version number in renditions of the book,
as reported by svnversion.

* doc/book/Makefile
  ($(BOOK_VERSION_SOURCE)): Generate a version.xml
  file that defines the output of svnversion as an XML entity.
  ($(BOOK_HTML_TARGET), book-html-chunk, $(BOOK_PDF_TARGET),
  $(BOOK_PS_TARGET)): Depend on the generated version.xml file.
  book-clean: Remove the generated version.xml file.

* doc/book/book/book.xml: Include the generated version.xml file
  and insert its svn.version entity in an appropriate place in the
  bookinfo element.
