Upgrade to Immutable.js 3

[andrew-d]

This upgrades to the latest version of Immutable.js. Thankfully, migrating was pretty simple - I only had to change one line.

Worth noting: I just tried using this in the browser, and I get this traceback from Immutable.js:

 iterable.length has been deprecated, use iterable.size or iterable.count(). This warning will become a silent error in a future version. Error

Looks like the error is coming from here, and is being triggered when I have a getInitialState() that looks like this:

  getInitialState: function() {
    return {
      someKey: Immutable.Map(),
    };
  },

Any thoughts on what a fix could be?

I guess this can be closed as soon as #22 is merged in.
