Title: Normalmap shader

Unify Normalmap shader parameters with the other shaders as described in #4256

Also removed the option to turn on/off physically based shaders, it is now just always on (although I am not complete sure this is the right decision, but I am following the recommendation here: https://github.com/mrdoob/three.js/issues/4256#issuecomment-31475535 )
