title: React linter airbnb proptypes array
body: <p>I have the following <code>PropTypes</code>:</p>
  <pre><code>SmartTable.propTypes = {
    name: React.PropTypes.string.isRequired,
    cols: React.PropTypes.array.isRequired,
    rows: React.PropTypes.array.isRequired,
  };
  </code></pre>
  <p>but the linter says me:</p>
  <p><code>Prop type &quot;array&quot; is forbidden</code>, how can I change it?</p>
