[chore] updated bower version and added storage-modal class wrapper

@tejohnso I released version `0.2.0` of style-guide-css which includes all the styling from `media-library.css`. This PR is just updating `rise-vision-style-guide` to `0.2.0` and I also added a `storage-modal` class to one of the wrapper `divs` – just to isolate the styles by sections. 

Could you please review and merge if acceptable. Thanks!
