See my discussion with Will in the PR.

Will work on testing overlay next.

Also type the status.

This matches better with the other routes.

Also add a missing authentication check to the path proxy web socket.

It will now redirect all HTML requests. Also it avoids req.accepts since
that's always truthy.

Previously it would have just given them the error HTML.

I added another reject that doesn't destroy the response.

This is mostly so we don't have to do any wacky patching but it also
makes it so we don't have to keep checking if the request is a web
socket request every time we add middleware.

Now async routes are handled!

This lets us actually wait for disposal before a graceful exit.

This is to ensure it doesn't hang around.

This makes it clickable from the terminal.

It no longer handles authentication.

Broke when converting to a loop.

That allows its use in entry.ts as well.
