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.
Hmm. This concept is hard to represent well in a demo! I find "wrong side" confusing here without being able to see the markup.

Maybe something more like "Floated left content" and "Floated right uncleared content"? LOL, maybe that's not any better...
