Spec sheet with all mallard elements

We will install it to /usr/share/yelp/endless/spec/index.page, this
is not on the regular search path so it won't appear in any search
results.

However it can still be run from the command line as
yelp /usr/share/yelp/endless/spec/index.page
Allowing design to QA style changes.

Aww you didn't like my jurrasic park easter eggs? Added myself and some more obviously made up spoof names.

I do want to keep on a couple authors and an editor as this is actually part of the spec sheet, the attribution will need to be styled so I want to make sure we show all the elements that can appear there.
