Sudden Death — younger Sims can also die in their sleep

v1.1.1
— Fixed a problem where a Sim who died by Sudden Death would still be considered alive in certain occasions.
   - The game read a Sim's death type before the mod had told it about the Sudden Death type, and replaced it with "none". The type now exists from the moment the mod loads, and on load the mod restores it on any Sudden Death ghost a save already lost it on.
— Fixed a problem when invalid values were set on the .cfg file manually or through cheats.
— Fixed a problem where deleting the .cfg left the mod running on silent defaults forever.
