MUX: Add line disconnect message when a simulated line is dropped due to DTR transition,

Browse source 
To promote clarity of experience, a user on a telnet connected line (which
supports modem control signaling) will receive a "Disconnected from
{simulator name}" message when a session is explicitly terminated by the
simulated system.  This allows the user to differentiate that case from the
simulator merely being powered off or otherwise crashing.  This behavior
mirrors the "Connected to the {simulator name}" message that is presented
when the connection is established.
