title: Change Bootstrap popover title when ToolTip attribute exists
body: <p>I have a button on my page like this:</p>
  
  <pre><code>&lt;button class="btn btn-small btn-success help-target" rel="popover" data-content="This is the help contnet" data-placement="left" tooltip="Click to submit this form"&gt;Submit Review to AMR&lt;button&gt;
  </code></pre>
  
  <p>I also have some JavaScript on my page like this:</p>
  
  <pre><code>function showHelp() {
      $("#overlay").show();
      $('[rel=popover]').popover({ 'trigger': 'manual', 'title': function () { return 'Help'; } });
      $('[rel=popover]').popover('show');
  }
  </code></pre>
  
  <p>I've tried setting the "title" of my popover in two different ways, one is in the javascript code using the 'title' option and the other uses the data-title attribute on the HTML element. However, what is actually showing up in the title of my popover is the content of the "tooltip" attribute on the button element.</p>
  
  <p>No matter what I do, I can't seem to override that. I need the tooltip attribute on the element because I want that to show up when a user hovers over the element. </p>
  
  <p>Is there an easy way to override the title that I'm just missing?</p>
