Subject: Switch from black to ruff format

Ruff is faster and if it supports everything that black supports than why not? I
did have to pull in a more recent version from unstable, but that's easy to do
now. And I decided to just go ahead and configure ruff by turning on almost all
checks, which meant I had to fix a whole bunch of things, but I did that and
everything is okay now.
