Blender Internal: Modify material property "Cast Buffer Shadows" to affect ray shadows also, and rename it to "Cast Shadows".

Browse Source 
This allows us to make materials that don't cast ray shadows.
Turning off this property can reduce the rendering time slightly.

Note: RNA path is changed to "use_cast_shadows" as well. The older
path "use_cast_buffer_shadows" still can be used as its alias, but
it will be removed after updating some addons.
