Run test in web browsers

[remojansen]

As reported by @endel there are some issues in some versions of IE we need to put in place some testing in real browsers to prevent this kind of issues.

At the moment we run the tests in bot windows and linux but in node.js not browser environments.

The issues in IE are caused because Function.name is not an standard in JS versions < ES6.

The good news is that function name is only used to provide developer-friendly errors and it will be fine to use the following:

function getFunctionName(f) {
    return f.name ?  f.name : f.toString().match(/^function\s*([^\s(]+)/)[1];
}

let constructorName = getFunctionName(func);

Beyond this issue we need to prevent issues in browsers and to do so we need to run the tests on a web browser.

The function.name issue was fixed #302 by but it has not been released yet.

Hi @endel,

Based on your feedback I have impelmented browser testing:

It is almost ready, all the integration tests are running on the latest version of IE, Chrome and Firefox on AppVeyor.

There two test failing on IE 11 once I get those two sorted I will merge and close the issue.

There might be problems in IE < 11 but I asume that everything can be fixed using polyfills.

Done by #316
