Removed incorrectly used id attributes.

You used the `id` attribute to embed resource IDs in your pages, but that is not how this attribute is intended to be used. The `id` attribute is not for identifying *a resource* (that is what URIs are for), but for identifying *an element in an HTML page*.  In your case, you could use it to identify the recipe search form that appears in each of your pages, by giving it an `id` value of `recipe-search`. (This basically how you are already using the `name` attribute, the only difference being that `id` can be used to uniquely identify any element while `name` can only be used to uniquely identify forms.)
