In "raw" view, the link back to the Space Root isn't shown

Summary: That is, the small-text link above the Page's title isn't there, so navigation becomes hard.

This will become more important if we start using the raw view as the official way to deal with browsers that have JS turned off.

Potential snag: if we put that there, will it get in the way of scraping sites that are scraping the text? Is that okay? FB, at least, asks us to explicitly provide the text to display, so it's probably not a problem there.
