Ignore Jekyll markup

[mrpotes]

In a Jekyll markdown file there is a header that defines post attributes at the top of the file, separated by ---, e.g.:

---
author: me
title: My blog post
layout: default_post

---

## My subtitle
{{ site.time | date_to_string }}

The Markdown HTML Preview and Markdown Editor should ignore content in this section (enabled by a preference?), and any content between double curly braces, {{...}} and curly-brace-percent, {%...%}. In the example above, the preview view renders the section at the top, and the editor displays the text from the underscore in default_post to the first underscore in date_to_string in italics, and doesn't render the heading in bold.

I guess that is exactly Markdown metadata,
that is address by #49
