BUG: Version 3.3.5 throws a JS syntax error in IE 11

[braffas]

In modules\ganalytics\views\templates\hook\analyticsjs.tpl

  function uuidv4() {
    return ([1e7]+-1e3+-4e3+-8e3+-1e11).replace(/[018]/g, c =>
      (c ^ crypto.getRandomValues(new Uint8Array(1))[0] & 15 >> c / 4).toString(16)
    )
  }

This function throws a syntax error in IE 11 which in my case blocked customers from checking out on IE 11 (and probably lower versions also). TBH that function looks scary as hell, i have no idea how to fix it.

That's because Uint8Array is not supported on ie and edge yet (and also es6 arrow function which is not supported on ie).

This function purpose is to generate pseudo-random uuid v4. It's safe to switch to another implementation:

``` function uuidv4() { var uuid = "", i, random; for (i = 0; i < 32; i++) { random = Math.random() * 16 | 0;

if (i == 8 || i == 12 || i == 16 || i == 20) {
  uuid += "-"
}
uuid += (i == 12 ? 4 : (i == 16 ? (random & 3 | 8) : random)).toString(16);

} return uuid; } ```

I've filed issue https://github.com/thirtybees/thirtybees/issues/584

Sweet! Thank you for fixing that :)
