Fixed Pesky Build fail realting to dates

Re-added the site-map from debugging removal.
Fixed a malformed date from the front matter
of a page.
Re-enabled useful but defaulted options.
Merge branch 'master' into develop
Added gem file to play with.

Relying on GH-Pages, it is imperative to follow
their spec.
