Working negosimulator.jar

Added etc/, agentrepository.xml, boarepository.xml, domainrepository.xml
and protocolrepository.xml which are used by negosimulator. Renamed the
agent files to Group1_(...).java as specified in the assignment. Added
the run configuration NegoGUIApp.launch, which starts the negosimulator
from Eclipse.
