World: big maps no longer run out of spatial cull IDs while loading

A spatial transaction queue gives every object it tracks a cull ID from a
free list made once, when the queue is, at the game's
InitialCullIdListSize (40,000 in its config), and never grown. A custom
map with more objects (Cardiff) emptied it while loading and the next
insert read entry 0xffffffff of the list (crash at 0x489cfe9).

- spatial_cull_ids: as each queue makes its list, its size setting is
  raised to 262,144, one ID for every entity slot the entity pages hold;
  a larger configured value is kept. 12 bytes an ID per queue.
- The contract checks the list maker and how it reads the setting; it is
  installed at startup with the other world pools.
