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.
@parlarjb @klamping Is this something one of you can take care of? There was some discussion about how to implement in #framework on 12/15.
