Added old deprecated services to DeltaRobotNode. Also rewrote the other services somewhat and changed some comments. Compiles but completely untested.
Fixed some bugs in the moveRelativePath_old service, added the DeltaRobotTest to cmake.
Fixes based on review.
Added service return messages to ROS_INFO
