Add JSON and XML support for Dictionaries

[OmarElabd]

currently outputs:

    "Dict": 
    [
        [
            "Key": "a",
            "Value": "apple"
        ], 
        [
            "Key": "b",
            "Value": "bear"
        ], 
        [
            "Key": "c",
            "Value": "couch"
        ] 
    ], 

should output:

   "Dict": 
   {  
      "a":"apple",
      "b":"bear",
      "c":"couch"
   },

Need to look at output when key is not a String but a non-value type object.
