Tje previous QOTD server was a shell script executed by inetd, calling
fortune and doing some shitty UTF-8 to ASCII convertion which did not
support special characters like dashes.
The new server in the module `bbs.qotd` is based on Python's
`socketserver.TCPServer` and supports UTF-8 as expected nowadays.
The quotes are still those found in fortunes-mod databases, but we now
read them directly from the data files in `bbs.fortune`.
