Running `leastbot > ~/.leastbot/public.conf` has a couple of problems.

[nathan-at-least]

. Bash redirection creates an empty file before the left-hand process generates output, so leastbot sees an empty config file and raises an exception.

. leastbot dumps the example file output to stderr, so even this fails: leastbot > /tmp/foo ; mv /tmp/foo ~/.leastbot/public.conf

Fix these usability issues.
