This commit revertsdb7ef3f025(though it keeps the year updates) After discussion with several people, it seems better to mention copyright owners explicitly. eg. https://reuse.software/faq/#vcs-copyright explains the issue of using VCSs to track copyright. Asdb7ef3f025only replaced mentions of my name with 'The Limnoria Contributors', this commit only needs to undo that + add one person who contributed to setup.py.
