Feature/now 339

The reviews button hasn't been moved so I've left the sort where it was before but with the new layout.
If we are going to use the aria-labelledby then I think we should have a more descriptive ID for the element it is attached to. Something like `li-reviews-sort-btn`. Also, be careful when using IDs on elements since a directive could be used multiple times on a page, however this one is less likely.
