nathan d9ca5b93df Fixed issues with UDP connection handling. Fixed issues with
registration order. Fixed issues with connection shutdown. Fixed
issues with explicit flush(). Added support for UDP session handling.
Updated broadcast discovery to return ports used. Added
connection.send(), which will use the best option to send
 data (TCP first, otherwise UDP).
