Returns a unique number for a light source update to stamp the corners it visits with. Lets update_corners() skip corners it has already seen without building an associative list.
Wraps back to 1 before hitting LIGHTING_MAX_UPDATE_STAMP, and clears every corner's stamp when it does, so an old stamp can never match a new one. The clear is slow, but only happens every ~16.7 million updates.
