"Flat Material" option added to Shiny Diffuse

Requested by a certain user. Flat Material is a special non-photorealistic material that does not multiply the surface color by the cosine of the angle with the light, as happens in real life. Also, if receive_shadows is disabled, this flat material does no longer self-shadow. For special applications only.
