spoonacular recipe search spice updated to latest Duck Duck Go API

@jagtalon after the last pull request got in the way of the latest update in the Duck Duck Go API (see here: https://github.com/duckduckgo/zeroclickinfo-spice/pull/495), this is the new pull request according to the new API. All better and bigger :)

Here a screenshot highlighting how spoonacular understands what "popular" means and therefore highlights the likes and ranks accordingly.

Another example, this time the user doesn't want to spend a lot of time, so we rank by the time it takes to make the recipe.
