DO NOT MERGE YET: Demo site V2

Looking for team feedback (copy, angular.js optimization) for the V2 style guide demo site. (rackerlabs.github.io/encore-ui/)

Going to continue submitting commits, especially those marked FIXME.
Hmm...right now these are directing back to http://localhost:9001/#/overview -- is there a way that they can direct to this layout page (so that if they're clicked they don't take the user somewhere else)?
