Title: [Config] Fix stylesSet YAML keys normalization

This PR fixes #114. I was not aware any yaml keys are automatically normalized. The only way to fix it is to use the `normalizeKeys` method which has been introduced in Symfony `2.2.0`. So, this PR bumps Symfony to this version and Symfony `2.1.x` is not supported anymore.
