Basic Home Page

[jlbellido]

We need to reproduce in Drupal the current Home page plus some minor improvements.

• [x] As user I want to subscribe to the newsletter from the home page with the same styles that we have currently.
• [x] As user I want to see the social networks (Facebook, Twitter, G+, Youtube, Instagram) of drupal dev days at the bottom of the home page.
• [x] As user I want to see the a header with the logo, dates and main information of the event at the home page. It should looks like the current website.
• [x] Add styles to the home page.
