title: html support for node mail module
body: <p>I have installed node mail module (npm i mail - <a href="https://www.npmjs.com/package/mail" rel="nofollow noreferrer">https://www.npmjs.com/package/mail</a>)</p>
  
  <pre><code> mail.message({
    from: 'sender@example.net',
    to: ['recipient@somewhere.org'],
    subject: 'Hello from Node.JS'
  })
  .body('&lt;h2&gt;hello&lt;/h2&gt;')
  .send(function(err) {
    if (err) throw err;
    console.log('Sent!');
  });
  </code></pre>
  
  <p>I'm sending html template under .body(). Its not parsing to html in the email.
  Does this module doesn't support parsing to html format?</p>
