Fixed ROS middleware semantic camera and partially fixed human control

Updating to MORSE1.0beta2, i found the ROS middleware for semantic camera not working 

Also the human avatar throwed errors wich mainly are caused by the new naming scheme of builder API. I fixed the naming-related issues so far, no more errors are thrown but still the human does not move although human.applyMovement( move_speed, True ) and human.applyRotation( rotation_speed, True ) are executed.

I will get back to the problem next week...
