Convert EJS to using JADE

[mohamedmansour]

EJS is really limited when it comes to designing pages. We want to use Jade templates because it allows us to do blocked templating

Jade code looks a bit odd to me. Why use it?

Reopen for discussion purpose :

I'm currently digging to Rendr (https://github.com/airbnb/rendr), a framework based on Backbone.js that can render views both client side and server side. Using Handlebars, so not a meta-language à la Jade but HTML esssentially

But this is a discussion we need to have about the whole app architecture..

I don't mind changing the template, I just changed it to jade cause ejs wasn't working well at this time.
