title: mediawiki add <script> to <head> section
body: <p>I have a mediawiki site and I'm trying to add <code>&lt;script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"&gt;&lt;/script&gt;</code> to the <code>&lt;head&gt;</code> section of the page. 
  I can't figure out how to do it. 
  I've tried adding     </p>
  
  <pre><code>$wgResourceModules['ext.mobile'] = array(
      'scripts' =&gt; array('filename')
  </code></pre>
  
  <p>to the extension and I've tried adding </p>
  
  <pre><code>$out-&gt;addScript('&lt;script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"&gt;&lt;/script&gt;');
  </code></pre>
  
  <p>to the skin but it isn't showing in the view source. 
  How do I do this?</p>
