First crack at a relay script, so hopefully this works for folks.

The UI itself is built with Preact, which is not something I've seen before in a relay script. Feel free to steal the skeleton if you want. It makes the actual UI code much easier to write.
Feel free to report bugs here or on Github.
Thanks to Ezandora for the choice override library.
