Replaced os.db.Builtins contents with the contents of os.layer0.Layer0 resource file and fixed the resulting havoc (at least most of it).
Much of the stuff in the previous Builtins version was already deprecated and did not exist in the database, which is
why the database initialization produced the "built not found" errors it did.

Also changed IProjectLifecycle.onActivated/onDeactivated to take in Session and be ran outside of a database transaction to allow
the lifecycle handlers to perform arbitrary read/write requests. This should fix Arto's issues with Eco.
