Upgraded docs - API, Guides, and so on

[jamesplease]

We did an awesome job at getting the current docs hosted on the site, but now it's time to think about the next step. I'd love to see the API I'm working on get hosted, and then have a separate section for guides, similar to how Ember has it broken up.

We could have guides for Getting Started, Setting up Your First App, Architecture, Wreqr, Views...so many things. But first we need the site configured to support it.
