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.
Re: FIXME, they're used in LBaaS modals like Enable Connection Throttling, but it's done via another class, `.summary`.
