title: UIBootstrap Tooltip Multiple Triggers
body: <p>Is it possible to extend the triggers for Tooltip from UIBootstrap to accept multiple conditions.</p>
  
  <p>For example I want my tooltip to close on 'blur' and 'click'.</p>
  
  <p>I have tried to pass in an array but this does not work</p>
  
  <pre><code>$tooltipProvider.setTriggers({"click": ["blur", "click"]});
  </code></pre>
