QNode refactoring

Move almost everything to private classes.
Assimp loading restored.
All examples working.
QNode hierachy is now handled through QObject::setParent, addChild,
removeChild are part of the private api.

Note: commented QChangeArbiter unit tests as they can no longer work with this
patch and will restore them when QChangeArbiter will have been made private.
