[xmlroff] Next xmlroff is 0.3.0

[Tony G. <Ton...@Su...>]

Hopefully I've checked in all of the code changes necessary to make an
xmlroff 0.3.0, but I still need to update and regenerate the
documentation and test the packaging, etc.

I also intend to make the examples/xml2003/fixup.xsl stylesheet into
something that can be installed as
/usr/local/share/xml/libfo-0.3/libfo-compat.xsl to make it easier for
users to munge their .fo files so they don't break xmlroff (which is
all too easy to do).

Regards,


Tony.
