The problem is that the operator<< was taking a non-const reference to the QDebug
object. This causes a problem as all other operator<< return a temporary.
Since every other roperator<< takes the QDebug by value, we should also take it by value
in this case.
Move the operator<< in qdebug.h because i don't want to #include qdebug.h from qobject.h
And move the qt_QMetaEnum_debugOperator to be in the corresponding .cpp
