That entire site is a major spoiler. I had to force myself to stop looking at it because I want to have some surprises left when the full game comes out. The person/s who created the site obviously gained access to the game files through a rooted console and slapped a UI on top of them. I'm all for developing third party tools to improve the overall experience of a game, but this is a little over the line. I'd be surprised if Bungie doesn't try to find a way to shut the site down. There isn't even any disclaimer stating that all of the images and information are the intellectual property of Bungie. Not cool.
