.gitignore is helpfull and css/screen.css is not used
Slight formatting adjustment
Conditionally show the featured items section.

The featured item section doesn't apply to me, and might not be
useful to everyone. The empty featured section isn't attractive so
let's remove it entirely if there are not featured posts.

I decided to remove the "regular" section head if there are no
featured items since there is no reason to distinguish them. I could
go either way on if that stays excluded or not.

Only show social profiles if there is a link

I want to have people share my stuff on facebook, but dont really like randoms adding me. Maybe thats rude, but facebook is a little more private than Twitter for example.

Only show social profiles if there is a link in the _config.yml file. If their is no link the social profile link will be hidden on index.html. The sharing option in the article page remains untouched.
