Add support for markdown

[varunkumar]

I don't see any plugin that supports markdown files. Please add support for md files. Let me know if there is a way of doing this.

I need more details and sample to implement the plugin. Please come up with the requirements and we will schedule the development.

I want a capability to parse and render *.md files. The plugin should understand markdown syntax and render HTML files for the same. The plugin can support Github Flavored Markdown (GFM) or some other standard version.
