- Fix: Get Item assignement: if no valid gridno is found, let the game find one upon loading the sector instead of risking a wrong gridno assignment

- Fix: When dropping an item in strategic inventory, height values are not set 
- Fix: When looking for a valid gridno to drop items t via strategic inventory, WORLD_ITEM_REACHABLE is not reliable, as updated map topology trumps this. Instead rely upon finding a valid gridno once the sector is entered.
- Fix: when searching for a new item dropoff gridno, search for new height too
- Fix: if items are spawned mid-air, the player cannot retrieve them
