title: Inserting Jquery script file
body: <p>Hy guys!
  On my site I noticed that on some pages I don't have a Jquery library included. But on other pages I see it in my head tag:</p>
  
  <pre><code>    &lt;head&gt;
          ...
          &lt;script type="text/javascript" src="/assets/fe9bd624/jquery.js"&gt;&lt;/script&gt;
          &lt;script type="text/javascript" src="/assets/fe9bd624/jquery.ba-bbq.js"&gt;&lt;/script&gt;
          ...
      &lt;/head&gt;
  </code></pre>
  
  <p>In my theme layout/main.php I don't have Jquery files in head tag. So question is: what controls inserting Jquery on my pages, and how to insert it on all pages. Thx.</p>
