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.
Adds gold to two reloading recipes.
Fix'd.
Changes stats on children's book.
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.
Apparently C:DDA's wordwrap function hates long names.
Changes honey's material type to 'null' and V8's material type to 'veggy'.

If milk is 'null' and eggs are 'null' why is honey 'veggy'. Also, why
isn't V8 'veggy'? That's all it's made from!
Also changes spoilage time on V8.

It shouldn't be spoiling any more than the cans of soda should be
spoiling.
Also fixes broth spoil time, for the same reason.
Switch casters on wheelbarrow for a small wheel.
Spoilage timers restored.
Clear game.cpp of references to veh->external_parts.
