Remove the <bookbiblio> element. The front matter is now correctly
inserted in to the output.

Fix the author information. Translators should just copy the <author>
element and subelements in to their translation.

Turn chapter 1 into a preface, removing the subsection.

<literallayout> -> <programlisting>, so that diagrams are preserved.

This still needs a lot of cleaning up (volunteers, anyone?) but it'll do
for the moment until I can scrounge some free time (some time around
December, the way things are going at the moment).
