Got shared project running again
Created appendKeyValuePair method in URLEncodeEventSerializer; tests work
Got shop and driver running on lab machine agian
lab 3: shared: Added note to TODO comment in URLEncodeEventSerializer
lab 3: shop: updated OrdersController to create an Event object and serialize
it with the URLEncodeEventSerializer.
lab 3: shared: added value to the Spring Component Annotation in URLEncodeEventSerializer
so that it can be autowired in the future without problems if/when other
event serializers are added. Had to do this since URL is all uppercase.
lab 3: shared & shop: changed EventGenerator.sendEvent to require and Event
object instead of the serialized event string; updated OrdersController to
pass the event to the generator.
