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 see the link here has a FIXME, but if you don't get to this before end of week, could you explain in comments on this PR what's in Support Services? I'm not sure I follow, and want to be sure I understand/know how to document if there's not time for you to take care of it.
