Objects and triggers for chests, barrels and, in short, containers, please

chimeric

The engine as it is has script objects and triggers for doors - just NearestDoor, SecondNearestDoor and so on, and they behave oddly. NPC don't always see doors right next to them but walk half across the area instead. But there are no triggers and objects at all for chests, barrels, book shelves and, in short, containers that NPC could use to find them and interact with them. There are only triggers that work from within containers' own scripts, on the inside. Please introduce some for the outside.
