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.
Should this go in the "Design Patterns within Encore" section?

Happy to grab a screen shot here if you need one, but I'm not sure I understand what's needed.

Also: is there a reason we aren't linking to staging elsewhere (like when we mention pages where examples of patterns can be found in Encore)?
