Note that we found a "bug" in browsers, using keyboard navigation.
First, focus the language selector.
When tabbing to the next anchor, the focus is lost and the next anchor
disappears, so the element focus goes into the void and the loop resets.

Really not sure about how to solve this.

This is a simple fix, but it does the job.

We'll use zepto instead w<hen we'll need the js goodies.

It should now work on browsers with javascript disabled.
We're using a nifty checkbox hack.

Perhaps we'll remove this eventually.
Still, for now, it kinda fills the blanks.

Syncscroll now uses `data-name` instead of just `name`.
Also, breadcrumb the way with Gherkin.

Hopefully.

(while solving another goulish git merge)
