Summary
runner.js for performance test should use Bessel's correction

It's kind of bogus to use standard deviation for sample size smaller than 20 (for most tests). We should use some unbiased estimates for standard deviation. As a starter, we can use Bessel's correction.

Also, I'd like to see stdev or some distribution metrics in the chart. This is another story though.
