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.
I would say:
"See the example below **which uses `type="error"`. Note that `type="error"` can be replaced with the appropriate message response style.**"
