Comment:

 proposed approach to solve this issue:
 - move convertXML method to fusion.js from AppDef.js and add a callback
 argument
 - requests that still return XML will be directed through convertXML to
 convert the XML response into JSON

 The GxSelection task is separate issue and just involves putting it into a
 proper namespace
