Also add the href data for active items to the breadcrumb template

Is there a reason to **not** add the `href` of an active item to the breadcrumb template?

It would be great to have the `href` in the template for active items as well.
I'm dealing with Google's Rich Snippets for breadcrumbs and there the `href`for the active menu item is needed.

I could also go and write a hook to achieve this, but that's for sure not the idea behind :)
