Removed debug Output from AgentManager.cpp
Refactoring rootSegment to bodyRoot, quick hack follow camera in action, Tests: the scene tests are now all done in the initTestCase(), MotionTreeManager stub

Follow cam ist just a quickhack! only follows agent root, not the root

Unit tests: all scene tests are done in initTestCase(), so that
following tests can rely on a checked scene and may be called
individually
