Adds a method to elements to get their event listeners

Per 30-01-2020. Zie de nieuwste versie.

Adds a listEventListeners method to every element that returns an array containing every event added to that listener.

Eg.

const el = document.getElementById("my-test-element");
el.addEventListener("click", doSomething);
el.listEventListeners(); // returns [doSomething]
