New global tag styles

New global tag styles across galleries and article pages ![image](https://cloud.githubusercontent.com/assets/2236852/4251857/9d4976d8-3a90-11e4-84fe-8dcc66d00f5b.png)

There are other files than just articleBody and galleryBody, such as: liveblogs, pictures, videos, interactives. 

I would consider abstracting this into ints own fragments to avoid duplication.
