title: textarea with a few editing options
body: <p>I need a simple text editor on my site, just with the following options:<br>
  - ordered and unordered lists<br>
  - heading or bold characters<br>
  - horizontal rule  </p>
  
  <p>Is there any way to get the above by coding, inside an existing <code>textarea</code> tag</p>
  
  <p>I tried with <code>contentEditable</code> div but there is a lot of problems there, for example <code>return</code> changes the format of preceding text and so on.</p>
