objectCentralisation implemented without positionManager methods
ObjectCentralisation extendet by a prescan to enlarge the scan radius up to 45 degrees
added a flag to the terminate command which differs if the connection
still exists and should be closed or not
robot moves 15 cm backwards and moves the picker down before terminating
if the command is received
the connection reset is now a bit easier and only depends on the
terminate flag
the Server queries the robot for it's current position if the connection
was reset
the Server prints the robot names in most System.out calls now
