Redesign of the frag part of unshadedNodes so it's more modular, and can be properly used as GLSL 1.5 shader.

Browse Source 
Added a stress test for unshadedNodes.
Changed the name of the texture parameter to textureMap in TextureFetch shaderNode as it was conflicting with the texture function used to fetch a texel from a a texture in glsl 1.5
