ONCE WHERE THE CLIENT AND SERVER WERE ON THE SAME MACHINE.
Client-side support for dynamic host discovery. COMPLETELY UNTESTED

Created a run-client-no-host task for running the client without a host,

EXCEPT FOR ONCE WHERE CLIENT AND SERVER WERE ON THE SAME MACHINE.
Updated the readme file for the extra credit option of not specifying a
host on the client.
