SCI: Blocking ScummVM auto-save slot 0 for saving
Auto-saving is not used by SCI, but slot 0 is ScummVM "standard" for auto-saving, that's why it's not available for saving anymore. Jones still uses slot 0 for saving/restoring (because it's hardcoded and changing it would break it somewhat) Deleting + restoring is still possible of couse.
