Contrarily to Q_OBJECTs, Q_GADGETs are not guaranteed to descend from a Q_GADGET. Here, we ensure that if the first superclass is a Q_GADGET, then the derived class will be treated as one. This allows gaps in the Q_GADGET hierarchy while preventing from trying to link to the inexistent staticMetaObject if there's no such ancestor.
