Flatten primary object key option for JTask::Convert

[adammcarth]

JSON files which don't use id numbers as a primary key (most of them) will more often than not have one that would make more sense if merged with its child (flattened) when an id is added in JTask::Convert.from_json.

employees.json

"John Doe": {
  "email": "[email protected]",
  "title": "CEO"
}

JTask::Convert.from_json("employees.json")

Current JTask Conversion:

"1": {
  "John Doe": {
    "email": "[email protected]",
    "title": "CEO"
  }
}

Seems a little stupid now, doesn't it? JTask::Convert should offer an option to flatten the parent key and merge it under a new key in it's child. Something like this...

"1": {
  "name": "John Doe",
  "email": "[email protected]",
  "title": "CEO"
}
