Fix lag during Hell Universe
Created by: clusterfack
- Found the major leak of atom/movable/overlay deletions, it was being caused by door/cultify
- Found the last major source of regular deletions, it was being caused by table/New() deleting any prior tables when cultify intentionally spawned tables on top of the tables
- Commented out horde because it barely works, it adds little since everything is already dead by this point, and it uses over 100% of the cpu of any server to run even normally. Related: http://www.byond.com/forum/?post=1288063
