Layout novo

CODE REVIEW needed. I'm not confident about responsive styles, it was very confuse to me. But it was tested at http://johnpolacek.github.io/Responsivator/

What is needed before merge: 
- Infinity scroll (we will take off the pagination).
- Content license I will find a place for it later :/
