Create backend and frontend for connecting scratchnet instances

[karel1980]

The connection process goes like this:

• Alice uses localhost:2000 to invite {Bob} for {chat}
• Bob receives the invitation (browser pops this up)
• Bob accepts the invitation (his manager starts comm.js and sends acceptance to Alice)
• Alice receives the acceptance and starts comm.js

yep.
I think you will need a 5th step though: after the service is started on Alice's side, you will need to communicate the allocated port back to Bob.

And I suggest we use some "connection-setup-id" to handle this messaging between Bob and Alice, just to make sure they could be simultanuously setting up multiple connections with multiple connection-peers...

Yes. I was aiming to put that in the response body of Alice's last step, but because of the async nature of the .listen() call we might need an additional call
