SetPlaceableIllumination

// Set the status of the illumination for oPlaceable.
// - oPlaceable
// - bIlluminate: if this is TRUE, oPlaceable's illumination will be turned on.
//   If this is FALSE, oPlaceable's illumination will be turned off.
// Note: You must call RecomputeStaticLighting() after calling this function in
// order for the changes to occur visually for the players.
// SetPlaceableIllumination() buffers the illumination changes, which are then
// sent out to the players once RecomputeStaticLighting() is called.  As such,
// it is best to call SetPlaceableIllumination() for all the placeables you wish
// to set the illumination on, and then call RecomputeStaticLighting() once after
// all the placeable illumination has been set.
// * If oPlaceable is not a placeable object, or oPlaceable is a placeable that
//   doesn't have a light, nothing will happen.
