NPCs generate trash when walking past trash cans

[FalloutFalcon]

About The Pull Request

Trashcans and dumpsters now listen to NPCs that walk by them, and upon walking by, assuming its the NPC's first time littering, will dispose of a piece of trash onto the can's turf.

Why It's Good For The Game

Flavorful, a source of loot for makeshift crafting and other junk, and a possible hook for a streetsweeper job.
