Update: provide breadcrumbs at current path and plan on having login-specific path handling

This provides breadcrumbs 'at feet' instead of 'behind feet'.
The idea is that the breadcrumbs will show the current path as well as the path history (based on site structure, not browser/navigation history).

Plan on having the login handler provide (and possibly conditionally so) the path of the current page instead of the login page.
The login handler will show up on different pages than just 'u/login'.
Those pages should display their breadcrumb path instead of the login path (unless otherwise hidden).
One possible method is to pass the parent handler's path to the child path.
