/ws and /wss -- websockets

If you want browsers to connect to e.g. /dns4/example.com/tcp/443/wss/ipfs/QmFoo

• An SSL cert matching the /dns4 or /dns6 name
• go-ipfs listening on /ip4/127.0.0.1/tcp/8081/ws
  • 8081 is just an example
  • note that it's /ws here, not /wss -- go-ipfs can't currently do SSL, see the next point
• nginx
  • configured with the SSL cert
  • listening on port 443
  • forwarding to 127.0.0.1:8081
