display: don't apply color-scale-via-lighting to shader inputs

Browse Source 
This isn't working properly at the moment, since the state gets set for the *next* object, causing significant artifacts.  I wasn't entirely sure whether to restore the "proper" behavior or not, since applications may be relying on one or the other behavior, but enabling this feature for shaders is a minefield and it's a lot better to just tell people to use p3d_ColorScale instead.
