Title: Added ability to retrieve file's sender

I might be wrong, but I didn't manage to find a way to know who is the sender of a file, so I just put the userid in the file's data in receiver's side.

Is this userid the userid provided by webrtc or is it an information given by the remote client?
If it is given by the remote client then it is insecure.
