Bug 33006: (follow-up) Add spans for translatability

Bug 33006: (follow-up) Add spans for translatability

This patch finds places in the updated breadcrumbs markup where a
translatable string is isolated in a way that makes it hard for the
translation script to find it, and wraps these strings with <span>

This patch also modifies some of the templates to simplify
the logic controlling how different elements of the breadcrumbs are
shown or not.

This patch also modifies another problematic set of strings in
auth_tag_structure.tt outside the breadcrumbs.
