Websocket integration

[th3l0g4n]

First of all: Nice work! I like the react / next approach very much.

Im going to setup a Dashboard using your Framework. But regarding Datasources I want the widgets to be updated via Websockets (because of some Security Issues / Rate Limiting / etc.).
I've created a simple node server which fetches data on regular basis and publishes the latest results to connected clients.

I've hacked around a little bit to integrate sockets and everything seems to be fine right now:

...
import io from 'socket.io-client'

const socket = io('http://somehost');

export default () => (
  <Dashboard theme={darkTheme}>
    <JiraIssueCount
      title='My Issues'
      socket={socket}
      event='myproject:issues'
    />

For me the given widget-url is irrelevant, but I can imagine that a widget potentially could determine by itself if it should fetch data via url (the current approach) or via websocket (and the given eventname it should listen to), depending on the props it was given.
