Bug in cardynamics.cpp particles load - wheels counted twice

[LBodnar]

If wheel weights are explicitly listed in .car file they are added to the particles list twice and therefore effectively double their input into weight and body inertia. Wheels with default weight are OK.

Code:

[wheel.fr]
...
mass = 40.0
inertia = 1.58

[NaN]

Confirmed. The wheel mass calculation code is to be removed. This is also going to fix this bug.
