Feat(dynamic): Dynamic content pages have been added (rather than
hardcoded HTML. This is Skipper dog fooding itself (I.E. Skipper
now makes requests to itself to pull content for these dynamic pages).
This commit also adds initial support for an "official" Skipper Go API.
This is nice as the API satisfies interfaces Skipper itself uses
internally (E.G. m/content, m/value).
