Upgrade the book sources to DocBook 4.4 (from DocBook Lite). We are,
of course, not making use of the full DTD, but we certainly can.

Minor, mostly-non-content tweaks for DocBook 4.4 compliance.
* src/en/book/book.xml
Tweak this for DocBook 4.4 compliance. Update the edition and
editor blobs, and unset the ISBN number.
* src/tools/Makefile.base-rules
(version): Reduce the svn.version entity definition to *just* the
output from svnversion. Add new svn.l10n_revision and svn.date
entity definitions.
* src/en/Makefile
(L10N_REVISION): Override the default value of "Revision" with just "r".
* src/en/README
Note the fact that we are using DocBook 4.4 instead of DocBook Lite,
and provide a URL to an online reference.
* src/en/book/styles.css
Fix the way authors and publication dates are rendered.
