We cannot use override in the Q_OBJECT macro, so tell Clang not to warn
about our lack of use of the keyword in the three virtuals that Q_OBJECT
overrides when the user uses Q_DECL_OVERRIDE in their own functions.
We can't use Q_DECL_OVERRIDE for two reasons:
1) because that would trigger the warning in any and all virtual
overrides the user may have in their own class (and most of Qt)
2) because when Q_OBJECT is used in QObject, it's not overriding
anything -- it's the base declaration
For #2, we could add a different macro exclusively for QObject that moc
would expand, but it's unnecessary work.
