[finished] Add a restart-anyway API to Config

It's possible to ignore the "user setting" for restart-now
and call doRestart(true) directly. This is intended for
use with specific UIs that make that choice clear for the user.

Hook up both [finished] and [finishedq] to the "traditional"
restart-if-the-box-is-ticked logic although the example
QML doesn't expose that box.
