Subject: [PATCH] Fix ODR violation for ShaderModelRendererInternals

ShaderModelRendererInternals is defined twice, once by ModelRenderer.cpp
and once by HWLightingModelRenderer.cpp. Having both in the global
namespace is a violation of the C++ One-Definition-Rule.

Move both definitions into their "parent" classes.
