QSortFilterProxyModel: honor the roles parameter of dataChanged
When the source model emits dataChanged, it may tell which roles
have been changed. That information was lost when using a
QSortFilterProxyModel -- the proxy simply dropped that argument
(meaning "all roles may have changed"). It's instead a good idea
to forward the roles argument, as it may minimize hits on the
proxy (on unchanged roles).
[ChangeLog][QtCore][QSortFilterProxyModel] QSortFilterProxyModel
now properly forwards the roles that have been changed when
the source model emits dataChanged().
