Let interior Lights stay on as long as doors are open

From the menu you can set the interior lights to stay on for a moment after opening the doors. But that time slot is way too short e.g. for taking things out from the back seat. So it would be better to a) keep he interior lights on as long as the doors are open b) automatically switch the lights off 30 seconds after doors are locked AND c) automatically sitch the lights off when the car is started
