title: Jenkins + GitHub Plugins webhooks not working
body: <p>I'm using latest (v1.10) Jenkins GitHub plugin, Jenkins v1.1
  My webhook integration fails with the error:</p>
  
  <pre><code>java.lang.IllegalArgumentException: Github Webhook event of type ping is not supported. Only push events are current supported
  </code></pre>
  
  <p>Looks like GitHub is using some kind of 'ping' events, that are not supported. Or there is some configuration missing?</p>
