Produce an embeddable stylesheet

[mojavelinux]

Produce an embeddable stylesheet that can be used where the AsciiDoc is rendered to embeddable HTML. This stylesheet should exclude any of the styling that is needed for the outer framing added by the header_footer option and focus only on styling body content.

There's a wip branch here: #2

This is also a related PR to wrap the styles in a CSS selector. #10 I think the styles that are wrapped should only be the "body" styles, hence why these two enhancements fit together.

Is this issue the equivalent to creating the embedded stylesheet to use with the Asciidoctor.org global website theme?

[mojavelinux]

Exactly.

We should probably have a flag on the build that includes the whole Foundation stylesheet or just part of it so that you can either use Foundation minimally or a complete integration (like for sites).
