title: MFMailComposeViewController : how do I embed a clickable URL link into the email message body
body: <p>I want my app using the <code>MFMailComposeViewController</code> to send an email such that the recipient can click on the embedded <code>url</code> to open the corresponding web site.
  <code>MFMailComposeViewController</code> does not appear to support this explicitly. Any ideas?</p>
