Version regressions in cosmic compared to bionic

[Julian Andres Klode]

I recently saw some packages in cosmic that have older
versions than the one in bionic, so I wrote a script to
check that, and here are the results.

I think we need to be more careful when it comes to this,
and regressions in security fixes (e.g. having a list
of CVE regressions in devel compared to stable).

The script used for this list is attached, I'd like to polish
it up a bit, add team info, make it generate html and json and
have it run periodically.

Note that the script compares released versions from the
old release to the new release. If there is a newer version
in proposed, it also mentions that, but still lists it.

-- script output:
