It's time for mjolnir-shell, a presentation style interface.

While this isn't a true presentation style interface,
the idea is that there is an argument stream to commands
that we pattern match commands against, and there are
different mediums that the commands can be invoked from.

There are translators between presentation types
and also between commands and mediums to do things like
render the result of the command for Matrix etc.

This is all inspired by the Common Lisp Interface Manager (CLIM).
But there are significant differences since, hello, this is
essentially being made for Matrix bots and appservices.
