Change component name to normalize-scss

I've changed the name of the component from normalize.scss to normalize-scss.

The old name caused Bower to save this component with its old name. Bower also has a component in its repo called "normalize.scss". So when installing all dependencies of a project via `bower install` Bower tries to install the wrong component.
In order to prevent this behavior I suggest changing the name in the bower.json file. For consistency I also suggest to rename it in component.json.
