[flexcoders] Adding more variable information to the FileReference.upload()

[Wally Kolcz]

I am attempting to upload photos using FileReference. It seems to work 
file, passing the file to ColdFusion to process the uploading, however I 
need to associate the username to the actual file (or its final name). 
Can I add a variable to the 'filedata' to include the username from the 
application so I can use it in CF to insert into the database?
