Apologies, my first time commiting code in GitHub.
Please review and use only commit "Merge pull request #1 from bennelson1234/addChromeDetection".
The commits "Update browser.js", "Add Chrome 56" and "Added Chrome 56" can be ignored as they have typos and I don't know how to un-commit them.

Hi @bennelson1234

Thanks for taking the time to do this!

Unfortunately your pull request is kind of a mess. Could you resubmit the pull request with only the required changes (without reformatting/indenting existing code). Thanks.

I would fix it myself by frankly I'm drunk and couldn't be bothered. It's likely easier/faster to submit a new PR.

Here's an example of adding support for a new browser version, albeit for Firefox: e95ef8f

I'll fix all this and get it right :-)
