Using Request node module to handle all the communication with github

I basically removed all in-house code that we have written to communicate over http from node to github.
It's now handled by [request](https://npmjs.org/package/request)

I also switched back to using original [highlight.js](https://npmjs.org/package/highlight.js). I inject dynamically the syntax file related to AT.

And last, I created a status page, that tries to list and display all the different usecases to be used for snippets and samples
