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.
!!! Love this. Is this vertical rule a new pattern (that we could use for big metadata sections)? I don't feel like I've seen it before.
