Modifications to the test suite to enable running as a cross browser performance test.
  js/index.js

How to update:

1. In js/index.js, change the 'step' attribute to add the required console.log
statements. Below is the patch.

2. In js/tests/sprites.js, apply the below patch to keep too many objects from
being created on fast desktop machines.
