Adjust 18f guild template to better support complex content

@noahmanger volunteered to take a crack at a design for this. The content that will need to go into the design is referenced in #15 .

@msecret where is the guide template again?

So when we add the CSS styleguide, for instance, we'll want a second level of navigation on the side.

I don't know how @noahmanger will solve the nav problem -- may or may not be on the side

Most of this is solved with #27, right? What's left @noahmanger ?

This is done.
