d5f1f59d77 The `https-port-number' configuration is meaningless, removed and 
replaced with `use-https' which defaults to #t.  If the web server is
disabled, run a tiny "server" that spits out a message -- to avoid
students complaining that something is broken.

Configuration files with `https-port-number' will throw an error, and
should be upgraded.
