feat: add 'q' as alias to quit to exit interactive roundup-admin Also require no arguments to 'q', 'quit' or 'exit' before exiting. Now typing 'quit a' will get an unknown command error. Add to admin-guide how to get out of interactive mode. Also test 'q' and 'exit' commands. No upgrading docs added. Not that big a feature. Just noted in CHANGES. Reporting error if argument provided is unlikely to be an issue IMO, so no upgrading.txt entry.
