Repository: webpack-contrib/css-loader (js)

Issue:
export classes (include `:global`)
if not use css-module, how to get class from file ?

``` css
//style.css
.block {width:1 00%;}
.block_mod {color: red;}
```

``` js
//index.es6
import slyle form './style.css';
//style = [
//  'block',
//  'block_mod'
//];
```
