working on Zigbee (CarClientManager) <-> Server <-> world (car detected by camera) integration.

Current issue to solve during debugging of WorldSimulator and Server implemenation: CarClientManager is instantiated twice and singleton is not shared among the two applications.

Start server on WorldSim startup
different default map size
different car scaling
improved 'add car' positioning in world simulator
cleanup
added project and lib dependencies
PlayerClient and PlayerCommunication now uses Java 1.6
improved logging
updated kyronet from 2.18 to 2.21
game start with simulators (player and camera simulator) now possible.
