Can't pass nested JSON Object

[WilliamMcCumstie]

I noticed when you want to pass a nested JSON object with put item (also update item), it insert the object into the database as [object, object].

I haven't started looking into your code in to mush depth yet, but as aws can support nested json objects, it would worth looking into.

Example
Trying to insert the following object into a new table won't give any warnings

var object = {
	"id": "id",
	"num": 1,
	"str": "string",
	"Obj": {
		"num": 1,
		"str": "string"
	}
};
dynode.putItem("NewTable", object);

However amazon will show it inserted as:

{
  "id": "id",
  "num": 1,
  "Obj": "[object Object]",
  "str": "string"
}

My guess it something to do with the stringify in the putItem method

var request = util.mixin({}, {TableName: tableName, Item: Types.stringify(item)}, options);
