Allow preConfirm to prevent dialog closing

on Node.js Yarn

Thanks to @dchekanov who raised the issue #896, now it's possible to prevent a dialog from being closed by returning false in the preConfirm parameter function.

Example:

preConfirm: function() {
  if (!confirm('Are you sure?')) {
    return false;
  }
  // proceed otherwise
}

or even shorter with ES6:

preConfirm: () => confirm('Are you sure?')
