Marc Mutz 3458cf984a QMessageBox: leave the Option's underlying_type as the default, int
QFlags<Option> will anyway store the value in an `int`, so we gain
nothing from choosing quint8 as the fixed type, except artificially
limiting the number of possible future options to eight.

Found in API-review.

As a drive-by, put options one per line and add a trailing comma where
possible.
