The system now keeps a tag of the last version (just an arbitrary string) that the setup wizard was run for. If this is different than the current one in the setup wizard, then setup is launched at boot. This introduces a new intent action for the part of the setup wizard that gets run for an ungrade, which the system uses to find its current version tag for comparing against what was last stored. It is up to the launched setup activity update the stored setting to reflect its current value, once it is happy.
