title: Do not add TITLE as heading to body when exporting org file
body: <p>This export option:</p>
  
  <pre><code>#+TITLE: My title
  </code></pre>
  
  <p>Does two things:</p>
  
  <ol>
  <li>adds a meta tag on the document's <code>head</code>: <code>&lt;title&gt;My title&lt;/title&gt;</code></li>
  <li>adds a heading at the start of the generated <code>content</code> <code>div</code>: <code>&lt;h1 class="title"&gt;My title&lt;/h1&gt;</code></li>
  </ol>
  
  <p>I want 1 but do not want 2. Is it possible to configure this?</p>
