created dummy client

I created a dummy client, and the nessicary dummy config class, to
comunicate with the arduino.  The dummy config will always produce the
same pump id, during a single execution, for an identifier.  The pumpID
returned id baised on the number of ingreidents already saved.
Dummy client

I finished off the dummy client, and fixed bugs in the drink and arduino
comuncator class.
removed debuging outpout in drink
