Attempting to test Rendering core's main test code

The crash happens in shaders.cpp at shader::shader() method, at the line
"HR(D3DXCreateEffectFromFile(g_d3dDevice, filename.c_str(),
0, 0, D3DXSHADER_DEBUG, 0, &m_FX, &errors));".  The revert to normal
code flow, comment out the Test(); line in GSP420MainCore.cpp, and
uncomment the other two.
