What changes

The two pictures in the README show urga as it is now, and make screens takes them again whenever the screens change. The client picture still showed <ctrl-d> Drivers, which is v now.

• scripts/screens.sh starts a Nomad agent in dev mode on ports 24646-24648, so it runs next to another local cluster, with a client named client-01.
• It runs the jobs in scripts/screens/: services in prod and staging, a job that waits for a client it cannot have, a batch job that completes and one that fails.
• urga runs in a terminal of 170 by 43 with an empty home, so the settings of whoever runs it do not change the pictures. The job list is taken at once; the client is taken after its charts fill for six minutes.
• freeze draws the terminal into a picture. It draws with the font it carries only when rsvg-convert is not on the PATH, so the script runs it without one.
• CONTRIBUTING.md says what make screens needs and how long it takes.
