Preparing stuff for DX11:

- be more strict with the input signature of generated pixel shaders
- replace the D3D parameter with an API_TYPE one, so that we can further distinguish between DX9 and DX11
- for what it's worth dx11 (using vs_4_0) doesn't support D3DCOLORtoUBYTE4; added a workaround for this
- add a "dx9-" prefix to the shader cache files to avoid conflicts with dx11 shaders

Apart from that we're calling CommandProcessor::Shutdown() in main.cpp,Shutdown() now.
Delete all files in User/ShaderCache if you want to save a few KB disk space :P
