lintian.d.o upgraded to 2.3.1

[Russ Allbery <rra@debian.org>]

I've upgraded lintian.d.o to 2.3.1, but I haven't regenerated the entire
archive.  This means that the warnings about upstream man page spelling
errors are still showing as warnings unless a new version of the package
has been uploaded.  I can regenerate the archive if it bothers people, but
that takes a few days.

I think this version should be good for propagation into testing unless
something urgent crops up, so I'm tentatively planning the next release
for the 16th, depending on whether we've accumulated enough changes by
then to make it worth it.
