Faux block links (1/2: on fromage and saucisson patterns)

To accomodate upcoming design changes where we'll have links between the item image and the title, here 

- [new] `.u-faux-block-link` CSS utility: see http://codepen.io/BPScott/pen/Erwan (thanks to @BPScott)
- [new] Entire surface of saucisson and fromage items are clickable
- [new] Byline is clickable in saucisson and fromage
