Title: Added plumbing for latency tracking

Essentially, we add a unique ID to each request. The client can capture this
ID and report back when the page has rendered sufficiently. Then we can know
a response time that includes client latency!

Based on idea at http://www.thumbtack.com/engineering/know-your-latency/
