Build a web-based emulator for the documentation site (#1597)
Historically we've used copy-cat to provide a web-based emulator for
running example code on our documentation site. However, copy-cat is
often out-of-date with CC:T, which means example snippets fail when you
try to run them!

This commit vendors in copy-cat (or rather an updated version of it)
into CC:T itself, allowing us to ensure the emulator is always in sync
with the mod.

While the ARCHITECTURE.md documentation goes into a little bit more
detail here, the general implementation is as follows

 - In project/src/main we implement the core of the emulator. This
   includes a basic reimplementation of some of CC's classes to work on
   the web (mostly the HTTP API and ComputerThread), and some additional
   code to expose the computers to Javascript.

 - This is all then compiled to Javascript using [TeaVM][1] (we actually
   use a [personal fork of it][2] as there's a couple of changes I've
   not upstreamed yet).

 - The Javascript side then pulls in the these compiled classes (and
   the CC ROM) and hooks them up to [cc-web-term][3] to display the
   actual computer.

 - As we're no longer pulling in copy-cat, we can simplify our bundling
   system a little - we now just compile to ESM modules directly.
