SetAngularVelocity in rotationalframe.h

[sebiastisch]

Sorry for again having to post such a little bug, but the effects can be dramatic.

Please replace

Code:

void SetAngularVelocity(const MATHVECTOR <T, 3> & newangvel)
    {
        angular_momentum = inverse_inertia_tensor.Inverse().Multiply(newangvel);
        RecalculateSecondary();
    }

with

Code:

void SetAngularVelocity(const MATHVECTOR <T, 3> & newangvel)
    {
        angular_momentum = world_inverse_inertia_tensor.Inverse().Multiply(newangvel);
        angular_velocity = newangvel;
    }

To not RecalculateSecondary is just a minor optimation, but what really matters is the world in world_inverse_inertia_tensor

This can lead to a very strange problems, should the function be used somewhere.
