When we'll have video previews, we'll still need the file name.

Since we'll still need 2 templates for when we have previews and for when we have no previews (because of the change to blob uri, we'll need real images), we can still keep these 2 templates if you want, however we need the filename in both but with a class to hide the filename node if we don't need it. I'd prefer to see the class on the most unnested div.

you can also keep only one template if you want, and we'll split them again in bug 889902
