Silent failure on missing worldparameter

I think an exception error/exception should be triggered if a world parameter is not defined in jme

In your j3md of choice

WorldParameters { WorldViewProjectionMatrix NormalMatrix ImNotGonnaTriggerAnErrorOrExceptionEvenKwandoThinksIShouldMatrixInverseTranspose }

I think it would be "safe" to trigger an exception/error if a worldparameter is missing/misstyped/not defined since the shader would not work anyways..
