Refractoring of options output

[fussel178]

Another structure of the parsed JSON output for the options attribute, for example:

         "options": {
            "activity": {
               "activityType": "recovery",
               "progress": 74.4,
               "processed": 15600512,
               "total": 20954112,
               "finish": 3.2,
               "speed": 27496
            },
            "bitmap": {
               "attr1": "value1"
            }
         }

Notes:

• The options attribute is always given and an object.
• Options are unique through attribute name.
• Missing options are not listed.
