Fix lag during Hell Universe

1. Found the leak of atom/movable/overlay deletions, it was being caused by door/cultify

2. Found the last major source of regular deletions, it was being caused by table/New() deleting any prior tables while cultify intentionally spawned tables on top of the tables

3. Commented out horde because it barely works, it adds little since every is already dead by this point, and it uses over 100% of the cpu of any server to run even normally.
