Completes FileTransfer according to Swiften.
S5BTransport Session still needs generic T.
FileTransfer, OutgoingFileTransfer and IncomingFileTransfer are made an interface due to the need of multiple inheritance in
IncomingJingleFileTransfer and OutgoingJingleFileTransfer. Corresponding documentation has been updated.
