Add Rudimentary Guides

This is the beginning of Guides. 
Guides currently only have an associated `crop`, `user`, and `name`.
TODO:
* Guide pages are currently incomplete and mostly static except for the name and author (hooray!).
* Foundation accordion is not working at the moment. The JS in included, but it's not watching the HTML elements nor collapsing/expanding them.
* Guide CSS should be converted to SCSS

Anyway this is a start! Please let me know what I can fix in the time being @rickcarlino  @roryaronson and others.

You're using id="overview" twice here, which may be contributing to Foundation's accordion not working.
