Calitko now (partially) supports the bye Gnutella packet. It reports support for bye-packet in the handshake and closes the connection upon receiving a bye packet. Calitko would not send a bye packet yet. In order to do so, the new function closeSession (CloseCode), member of PacketSession should be called at the respective places (e.g. when a bad QRP patch is received, when packet reader reports detects a protocol desynchronization, etc.).
