Title: send deltas between sequential navigation.timing events

one way to implement #14 - would like to put tests around this but not seeing anything existing around sendPagePerformance. Could also be a separate method and configurable as discussed.

used standard set of events to avoid browser misimplementations or additions (msFirstPaint). Ignored unloadEvent since that depends on the previous document and is not always in the same sequence.
