`Body.create` ignores `anglePrev`, `area`, `mass` and `inertia` when they are 0.

In Body._initProperties (a subroutine of Body.create), the anglePrev is set to: body.anglePrev || body.angle.
This means that when an anglePrev of zero is given, it is ignored.
The same is true for area, mass and inertia, but this is slightly less important since those values are generally positive.
Possible fix
use ?? instead of ||
