 Currently, the ApplicationDefinition.js will create the widget instances
 and its Jx UI widget based on the widget's uiClass property. However, the
 options passed into the Jx UI widget constructor are always:

  * label
  * image
  * imageClass
  * toggle

 There should be another property like the uiClass that we can put extra
 initialization options onto that is merged with the above properties to
 form the final initialization options that is passed to the matching Jx UI
 widget constructor.
