Add startup tests that log start script, domcontentloaded, and onload.

TabContents sends a notification which is picked up by the browser
automation controller which keeps a map of events and times.  Add
an automation IPC so that tests can get these values from the
browser automation controller.  Finally, add a feature startup test
to collect these values.

This is just to get some consistent timings from the buildbot.
