Translatable Docbook and Gnome Tour

[Murray Cumming <murrayc murrayc com>]

Danilo, I'm trying to add some docbook->po->docbook->html generation to
gnomeweb-wml, so we can have a full GNOME tour at www.gnome.org/tour/, a
bit like the release notes.

I remember that you did the xml2po Makefile stuff in
releng/2.x/2.10rnotes, and you said that it would have been easier with
a different directory structure. I've added some stuff to gnomeweb-
wml/tour. Could you take a look, and maybe even modify your stuff so
that it generates the html for translated stuff?

At the moment, it just builds the english html with "make html" in
tour/.

Try not to make it do anything in the default build target, in case we
break the build.
