Breadcrumbs

Is a simple helper function for generate a breadcrumb. I wrote it for my own projects because I didn't want to use a class for the breadcrumb section. I thought just a helper function would be more efficient with less overhead.

Also, please pay attention to the generated markup. I used that nested lists because seems to be meaningful for describing hierarchies (search engines would appreciate it).
