Remove radeox

Radeox is a rendering engine for an unspecified markup.
Its [website](http://radeox.org/) is dead, the website
of its [authors](http://www.codehaus.org/) is dead too,
its [last commit](https://github.com/codehaus/radeox) was 13 years ago.

It's only used for the welcome and login messages,
as well as comments from users. If we want to have some markup parsing,
we should use something maintained with autoescaping guarantees,
instead of a piece of zombie code prone to $DEITY knows what injections.
