Add Org-Markup option.

[timoc]

Org mode markup is asgood as, if not better than markdown. With org-markup notes becomes more like Evernote on steroids. Org markup has everything markdown has, but includes agenda/TODO management, checkboxes, document workflows, topic tagging, tabular views based on topic properties, code snippets and active documents based on embedded scripts and more. It is at least as capable as XHTML, but as simple as markdown to use.

Here is an example org-document parser: https://github.com/mooz/org-js

It is also supported by github and other platforms, for README's and supported by pandoc to generate documents.
