test: add tests for chrome v53

[wseymour15]

Description

Note: Dependent on the changes in videojs/videojs-generate-karma-config#44

This, along with the change in the karma config generator, adds an additional test suite for Chrome v53. We need this to ensure we test a viable version of chrome for SMART TVs.

Specific Changes proposed

• Logic to use the older version of sinon when testing with Chrome v53
• Adding that older sinon package to the test modules with an alias.

Requirements Checklist

• Feature implemented / Bug fixed
• If necessary, more likely in a feature request than a bug fix
  • Change has been verified in an actual browser (Chrome, Firefox, IE)
  • Unit Tests updated or fixed
  • Docs/guides updated
  • Example created (starter template on JSBin)
• Reviewed by Two Core Contributors

Note that we need to update the videojs-generate-karma-config version before this will work.
