Add an ES6-friendly way to register "should"

I suggest adding a file named should.js at the root of this project that auto-registers ‘should’, i.e. require('./index').should();.

/* CURRENT SITUATION */

  // commonjs style looks nice
  require('chai').should();

  // but es6 isn't so nice
  import chai from 'chai';
  chai.should();

  // or you can do this, but it's still 2 lines
  import {should} from 'chai';
  should();

/* PROPOSAL */

  // single-line way to register 'should' in ES6
  import `chai/should`;

  // nb. other libraries use this convention too
  import 'babel-core/register';
  import 'coffee-script/register';

Note: people sometimes think side-effecting imports feel dirty, but it’s arguably less dirty than a globally side-effecting function call like .should(). When you have a ‘fromless’ import that doesn’t assign any variables, the syntax is explicitly intended for side-effects.

After combing the pr’s I found this and it worked.

import "chai/register-should"

Maybe the documentation needs to be updated later.

@jonaswindey this should be released as part of 4.0.0, which will be out soon 😄
