Added method to take care of the details of ownership transfer to C++.
Simple ownership transference, i.e. without parenting, is now performed by the new BindingManager::transferOwnershipToCpp method. It remove the parent of the transfered object and proceeds transfer or invalidation if needed. The generated code for simple ownership transfer from Python to C++ now reflects this change. Fixed the method BlackBox::keepObjectType that steals an ObjectType ownership to C++ to remove it from its parent also. The BlackBox class does not take care of the stolen object as a proper parent would, but its destructor deletes the object, so the "unparenting" is needed to avoid freeing the same memory twice. Created an unit test that adds children to a parent ObjectType and then steal the children to C++ with BlackBox.keepObjectType. Reviewed by Hugo Lima <hugo.lima@openbossa.org>
