Problem::getState() in ProcessorMotion::process()

This line (~L304) in processor_motion.cpp: last_ptr_->getFrame()->setState(getProblem()->getState(getCurrentTimeStamp()));

Calls problem to compose the state. Is this really necessary? I think this is not efficient. @jsola, consider this in your refactoring

    last_ptr_->getFrame()->setState     (this->getCurrentState());

Will get merged with #287 (closed)
