Vehicle Rebalances & New Content

Rebalanced all cargo containers to have varying sizes, a floor trunk no
longer has the same storage space as a trunk, and a trunk no longer has
the same storage space as a minifridge.

Rebalanced vehicle skins and frames
Most vehicles have been rebalanced to be far less sturdy but far more
lighter. Stronger versions are now "Heavy Duty" and used by a handful of
vehicles.

Rebalanced engine spawns
No more finding a V8 engine in the first car you come across. Most cars
use inline-4s now.

Rebalanced Gas-Tanks (And added two more)
Gas tanks now hold proper amounts of fuel, motor cycles no longer hold
as much as a car.

Added V12 Engine & Sports Car
Added Military Composite Plating
Added Armored Tires
Added Reinforced Headlights
Added Luxury RV
Added "Cheap Cube-Van" (Much slower and more common than the original
Cube Van)
Added Vehicle Table (A vehicle clutter item, useful for firewood
however.)
Added Electric Scooter
Added Humvee
Added M2 Browning (Requires special conditions to fire without vehicle
mount)

...and more!
Adding space after ellipses
Fixes and HD Frame Recipe

Ding
Add back the double-spacing after periods

Only to my previous changes.
Removed "Somehow, they're still edible." from french fries description

Because it's illogical since they can be rotten and with the "rot" state
in the description that might say its rotten if its actually is thus
making it really inedible.
