clamp spot angle to 179,

up custommaterial inputs to 16
add Material::PhotometricMask:handling to processedcustommaterial
and for paranoias sake go ahead and be explicit about _getLightMaterial (those *should* be unneeded as they optionally default to that, but it's how they were in the beatup fork during testing)
