Log Message
Add option to use different methods for retrieving a timestamp.
* Animometer/developer.html: Add performance.now and Date.now options.
* Animometer/resources/runner/animometer.js: Default to performance.now.
(window.benchmarkController.startBenchmark):
* Animometer/tests/resources/main.js: Tie the desired method to _getTimestamp.
(run): Use _getTimestamp.
(_animateLoop): Ditto.

Allow adding any number of markers to the graph. The markers can be labeled
and contain timestamp and sample index data. Make it a part of the controller
rather than keeping it in the sampler.
