Improve bookmarking title and header with full menu paths (#54) 

Pull request for review.

This is the work to add full menu paths to the dashboard, as per my earlier commit discussion. All changes as per code review have been made. Also:

- I believe we get the initial build free on page load, as a by-product of it loading #/functional
- if the server is ambiguous it will still do its proper "Menu - Sub Menu" thing
- I need to check the new /detail and /failures additions with tests in sandbox
- the function is called first in each report to eliminate any rendering delay, however small
