Prevent Electron app from redirecting when drag+dropping items in window

A concise version using ES6 syntax (working for me under Electron 1.4.1)

document.addEventListener('dragover', event => event.preventDefault())
document.addEventListener('drop', event => event.preventDefault())

Found a fix for Windows Electron v2.3.1 Windows Electron v0.30.0 the code should have listeners for both dragover AND drop.

  document.addEventListener('dragover',function(event){
    event.preventDefault();
    return false;
  },false);

  document.addEventListener('drop',function(event){
    event.preventDefault();
    return false;
  },false);

Electron will still redirect to the dropped file if you only listen to dragover or drop.

Cheers!
