Title: Add javascript timing metrics to timing panel onLoad if available

Some browsers support navigation timing via javascript. Since these metrics fit the category of timing, this commit adds a section to the timing panel containing key metrics from the browser performance timing object triggered soon after the onLoad event.

The change is plain javascript, so no library dependencies.
