Simplify the project repo

I was looking around the project, and really liking it. I thought that the Gruntfile and other js specific code in the repo are not needed. Removing it would make the repo lighter and also making it more understandable for first time users and people not used to grunt and co. Also moving the index file and content to index.md make it's feel more 'jekyll' like and remove one file from the repo. What do you think?
