Title: Do not include unuseful comments when precompiling assets

The head of the CSS file uses "/*!". It prevents Sprockets to delete the comments for the final asset CSS files. All those comments are outputed to the final CSS file like this:
```
...(blah blah blah)/*

```

It's a bandwidth waste for production environment. Let's remove it.
