Big UberShader update
-Added GRAPHICS_MAX_LIGHTPERPASS macro -Added glGetActiveUniform OpenGL function -Added (Uber)ShaderLibrary -Added (Uber)ShaderName parameter to models -Changed uniform system -Fixed Node copying -Moved Material class to Graphics module -Optimized lights -Remade Shader class -Renamed Node::Invalidate to Node::InvalidateNode -Renamed ShaderProgram to Shader Former-commit-id: 15f0cad52969e91a2442e7d750ba2dc412f3549d
