* Adds `BeforeSerialized` for entities to handle cleanup. * Adds `Created` and `LastSerialized` fields to all entities. While this is a big bloat, this will be necessary for identifying dangling references to other invalid entities. * Changes formula for determining a valid reference to be _not null, not deleted, and reference's created date must be at or before the entities last serialized date_. * Adds versioning to idx file and serializes `Created` and `LastSerialized`. * Fixes Save Stats and also disables it by default. |
