#2 file transfer

[Mike Townsley]

Add a file transfer facility to jYack. This would require
some fairly significant work since the clients should
facilitate file transfers directly between two clients and
NOT involve the server. Currently, the
net.madllama.network package CAN handle this. The
Network class can listen on any number of ports and
thread of a connection that handles data on any
protocol. However, the Client GUI was written to listen
to ALL CONNECTED and CONNECTION_CLOSED
ConnectionEvents as if they were all for the server.
That will all need changing since another client
connecting to THIS client would generate these same
events. There are ways around this, not sure which to
take at this point
