Made the format links mimic rss/atom feeds

The most common format links are rss/atom feeds, they
are usually white text on red/orange background.

But it wouldn't fit the general color theme or it would
confuse users, so what i suggest is white on light blue
background - but we also include a small 3d effect ;)
