More junk food

French fries, malted milk balls, peppermint patties, and Necco wafers.
Whoops, not my idea

Reviewed the IRC and the fries were Rivet's idea originally.  Struck
from my PR as there are far too many instances of men stealing women's
work already.
Add the small storage battery and minifridge.
Add a whole bunch of carts.
1/24 chance of a welding cart in a garage.
5/6 chance of a hotdog or ice cream cart in non-basketball parks.
Spawn wheelbarrows in and around hardware stores.
Spawn luggage carts at hotel entrance areas.
Add swivel chair spawns to offices and office towers.
OK OK

Fries are back and I think the item_groups is handled.  Now I've gotta
actually see if it works.
Switch casters on wheelbarrow for a small wheel.
Removes weird exclusionary rule that made many storage items and armors ethereal.
Merge more carts and armor fix.
Merge PR #3510 - More junk food
