Adapt for main page

Hi all,

@snakefooc will be helping us to improve this documentation site, and he had the idea to change the scope of this site, and probably in the future convert it in a home pages to link our open source projects.

In order to fix git hub pages generation in organization pages (like https://makingsense.github.io), and user's forks (like https://andresmoschini.github.io/makingsense.github.io) I had to take advantage of the new [Github Pages repository metadata](https://help.github.com/articles/repository-metadata-on-github-pages), so it also fix #23.
