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.
So I know this is a demo and we don't really expect people to click on these actions and have them do real things.

BUT right now if you click on them this happens:

and then you're unable to get back to the demo page (because the modal is too tall to close).

Could we make it a little less broken in case someone does click the action links?
