Bug: Inherit Velocity cannot be disable in Killable

Because deathPrefabKeepVelocity is not used in Killable.cs...
A fix can be:

if (spawnedDeathPrefab.rigidbody != null && !spawnedDeathPrefab.rigidbody.isKinematic
&& body != null && !body.isKinematic && deathPrefabKeepVelocity)
{

spawnedDeathPrefab.rigidbody.velocity = body.velocity;
}
