Consumer now exists with CLS.

- Consumer now sends a CLS before closing. We tell Master to tell the connections to ignore the quit event. Instead, the consumer does a broadcast of CLS to all connections, waits for the responses, and then sets a "force quit" event which the connection read-write loops -must- listen for. Since the connection-audit loop has already terminated by this time, no new connections will be made.
- Moved all remaining annotated constant values to config modules.
- Refactored code to be a little more intuitive.
