added all the files needed for sending and receving files using TCP. As well as bandwith counter, events, md5 checksum calc etc.
can now click send file, select file, get the selected peer from the listBox with the guid, ip and port. Next step sending the UDP packet
Sending file info works, sends name, md5, filesize, listen port etc. The listener also receive this file information. Next the UDP responder will request the new file. (in the future the peer will check if it already have the file or want the file before requesting it.)
udp listener is handling the file info object well. Get the file name, size, md5 etc all works.
bump version file_trasfer and f_join
