Utlizing Markdown for the Work Project files instead of raw html / increase ease of use and utilize power Jekyll

Travis, 

In effort to utilize the power of Jekyll and it's use of Markdown, I changed work projects files from html to markdown. I also adjusted the functions javascript file so it would read the rendered markdown files as HTML.

Hopefully this would bring added value to your project for DevTips. 

I have learned very much from your series and love the workflow that you have shared with everyone. It's very helpful indeed!
