Arvados

As an anonymous user is navigating through a public project, navigating to a collection or pipeline instance results in difficulty finding / going back to the project.

This was even more glaring as I was using the public project documentation. http://doc.arvados.org/start/getting_started/publicproject.html

This is because we hide the project breadcrumbs in anonymous view.

Instead of hiding it, we should show a version that is suitable for anonymous use, like:

• Instead of a "Home" link, first breadcrumb is just static text "Public projects".
• No dropdown.
• Link to parent project(s) of current object.
