Title: Add Bye message to protocol

Bye messages are used to close the TCP port, that has been announced via a HI message before.
A Bye message replaces the need to send many FileAnnouncements with TTL=0 to signal,
that these files are not availiable any more.

Implementation of Bye messages is optional (SHOULD).
