This commit reverts db7ef3f02517f9f2a3c56829a22b9fad3c36e374
(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.
As db7ef3f02517f9f2a3c56829a22b9fad3c36e374 only replaced mentions
of my name with 'The Limnoria Contributors', this commit only needs
to undo that + add one person who contributed to setup.py.
I disallowed it in f3f628ddba1dd640fde5db8b3defa72e54393ef7 because they
couldn't be deserialized properly.
This commit adds a new 'phrases' config var in addition to 'words',
that is comma-separated instead of space-separated.
