Provide tab and menu item to country index

There is no tab or menu item to go back to the country_code index that list all the countries. So when you're editing a country, there's really no way to go back to the country index except by going back using your browser's back button or by manually altering the url.

The breadcrumb is always this: Home › Administer › Site configuration. I would expect at least a › Country code added to the end.

When editing the languages from a country, for instance at admin/settings/country-code-country/us/languages, the breadcrumb is Home › Administer › Site configuration › Edit country. While the "Edit country" link is correct and valid, the link to the country index is still missing.
