title: Eslint errorring importing jsx without extension
body: <p>I am trying, in es6, to import jsx files without requiring the .jsx extension:</p>
  
  <pre><code>import LoginErrorDialog from './LoginErrorDialogView';
  </code></pre>
  
  <p>Not:</p>
  
  <pre><code>import LoginErrorDialog from './LoginErrorDialogView.jsx';
  </code></pre>
  
  <p>While I have got webpack to import in this fashion successfully:</p>
  
  <pre><code>export default {
    entry: './src/ui/js/app.js',
    output: {
      publicPath: '/',
      filename: 'bundle.js'
    },
    resolve: {
      extensions: ['.js', '.jsx'],
  </code></pre>
  
  <p>Eslint (<code>esw webpack.config.* ./ --color --ext .js --ext .jsx</code>) is still errorring.</p>
  
  <p><code>Unable to resolve path to module './LoginView'  import/no-unresolved</code></p>
  
  <p>Any ideas?</p>
