Heads Up Display (HUD) for development

[thescientist13]

Overview

As Greenwood is being run during development, users are naturally looking at their browser or IDE. However, when terminal errors happen, it often takes a while to pick up on that. It would be nice if maybe a server / resource based plugin was setup that could broadcast NodeJS errors to a little overlay that could be injected into the user's UI.

Thoughts

Basically establish some sort of web sockets, send a bunch of HTML, and have it display in a toast or some sort of unobtrusive pane.

This could be configurable

module.export = {
  devServer: {
    hud: true|false // what should the default be?
  }
}

So landed an initial concept of this in #750, but certainly more opportunities here to maybe create a general system for relaying communications back to the client, like through web sockets, and for all plugins? 🤔
