fix(level): change scene object config as the client does while loading it

ReadLvlObjectData (1.10.64, 0x0103ba20) changes an object's config as it
loads it:
- before version 47 a respawn time is in milliseconds: a float over 100
  or any u32 becomes that many seconds, as a float;
- a model spawner (LOT 176 with spawntemplate 14) gets its subkey as its
  blueprintid unless it has one, DisableModelBehaviors true unless set,
  and preventRenderWrapping true;
- before version 44 an object with sceneIDOverrideEnabled gets
  sceneLayerIDOverride 0.

LevelFile now makes the same changes. On live worlds 1906 spawners in
114 scene files of versions 45-46 have a u32 respawn time; the world
already divided those by 1000 but as an integer, so they now keep their
fraction (a 2500 ms respawn is 2.5 s, not 2 s). No live scene has a
model spawner; 62 objects of version 43 scenes get sceneLayerIDOverride.

Check in game: enemies and smashables respawn after the same time as
before on Forbidden Valley, Avant Gardens and Gnarled Forest.
