Not able to set up the Uploader in an "already uploaded" state

What steps will reproduce the problem?
1. Adds an uploader on a page (simple or multiple).
2. Uploads some files and change page
3. Go back to the previous page

What is the expected output? What do you see instead?
It could be fine it we could see the page in the same state as items were just 
uploaded. With button to remove files on the server, file informations, ...

But there is no way to reset the uploader in an uploaded state. The attached 
patch resolve this. The user has to call on an uploader instance the method 
setUploaded(info) where info is an instance of UploadedInfo.

Example on a multiuploader

MultiUploader defaultUploader = new MultiUploader();
RootPanel.get("default").add(defaultUploader);
defaultUploader.addOnFinishUploadHandler(onFinishUploaderHandler);

UploadedInfo info = new UploadedInfo();
info.name = "image.jpg";
info.ctype = "image/jpeg";
info.size = 56339;
info.field = "GWTMU-07915078044529884";
info.message = null;
defaultUploader.setUploaded(info);

The finished callback will be called, just as if the file was just uploaded.

What version of the product are you using? On what operating system?
trunk - rev 925

Please provide any additional information below.
It's the first time that I submit a patch on google code project. Maybe that 
there is a better method than a patch file ?
