Egregious hack to add date and base64 types to JSON for XML-RPC

rpcCall.json

{
	"methodCall": {
		"methodName": "examples.echoParams",
		"params": [
			"#dateTime=2018-06-10T19:41:06.199Z",
      			"#base64=aGVsbG8gd29ybGQ="
		]
	}
}

rpcCall2.json

{
	"methodCall": {
		"methodName": "examples.echoParams",
		"params": [
			{
				"#type": "dateTime",
				"#value": "2018-06-10T19:41:06.199Z"
			},
			{
				"#type": "base64",
				"#value": "aGVsbG8gd29ybGQ="
			}
		]
	}
}

Richard, the consumers wouldn't have to look inside the value to get the type, because that would be handled by the toolkit, as it is in XML-RPC's XML serialization.

JSON doesn't have a way of representing dates and binary info, but JavaScript does.

Another example based on a similar idea.
