WebSocket transport

I'm putting the cart way ahaad of the horse here, but maybe sometime in the future it might be beneficial to add a packet transport through WebSockets. This would primarily be useful for emulators implemented in Javascript, of which there are none yet.

I assume this would be quite easy using the stream socket interface (see NCP.md). An experiment could be to get the terminal emulator you use connected over Chaosnet, via a local cbridge on the host serving the terminal thing?
