Added water surface culling to bunker entrance as the direct well may show it close to shore
Ladder volumes, food crate spawners, bunker hatch uses rendererlod, smaller alpha carve surface
Lowered the bunker entrance 25cm to match the 3m grid down
Updated dungeon_grid_test, entrance scenes
Removed old entrance autospawn (still available as a manual placement inside monuments)
Created a static variant of computer station, although this will need work still
