Qt: Delay user confirmation of send

I made a subclass of QMessageBox that disables the send button in
exec() and starts a timer that calls a slot to re-enable it after a
configurable delay.

It also has a countdown in the send/yes button while it is disabled
to hint to the user why the send button is disabled (and that it is
actually supposed to be disabled).
