Subject: [PATCH] docs: update examples (#2319)

Since I was going through these anyway to ensure they work with [0.37](https://github.com/ipfs/js-ipfs/issues/2192) I've updated the examples to use the new [`IPFS.create` constructor](https://github.com/ipfs/js-ipfs#ipfs-constructor) and switched to using the promised API so that we onboard new users to using promises and minimise the disruption caused when https://github.com/ipfs/js-ipfs/issues/1670 bubbles up to here.

 We also need to make sure our go node can be dialed from the browser. For that, we need to enable a transport that both the browser and the go node can communicate over. We will use the web sockets transport, although there are others that can be used, such as `webrtc-star` and `websocket-star`. To enable the transport and set the interface and port we need to edit the `~/.ipfs/config` one more time. Let's find the `Swarm` array and add our desired address there. I picked `/ip4/0.0.0.0/tcp/4004/ws` because it is a port I know is not being used by anything on my machine, but we can also use port `0` so that the OS chooses a random available port for us — either one should work.
