/**
* Handlers for responses to uploads.
* Some tools will have to fix ids for generated content to ids
* returned by the server.
*
* The handler will be called with the following parameters
* $1 - sentObject		- The original data String
* $2 - responseObject	- The response from the server after the upload
*
* The handler should return a string or object representing the
* fixed data.
*
* Example
* function myUploadHandler(sentObject, responseObject){
* 		var string = JSON.stringify(sentObject);
*		// Replace Ids
*		for(var oldKey in responseObject){
*			var newKey = responseObject[oldKey];
*			var regEx = new RegExp(oldKey, 'g');
*			// Replace all instances of the old key with the new key
*			string = string.replace(regEx, newKey);
*		}
*		return string;
* }
