title: how to change the height of ngdialog
body: <p>I want to set size of <code>ngDialog</code>.  When I write the code below</p>
  
  <pre><code>ngDialog.open(
      template: 'adddUserDialog',
      className: 'ngdialog-theme-default',
      width:800px,
      height:800px
  });
  </code></pre>
  
  <p>I find the height configuration doesn't take effect but the width configuration works properly. Maybe <code>ngDialog</code> open function doesn't support the parameter of height.</p>
