Outdoor light to caves

[JP_Finn]

I was contemplating posting this in bugs vs suggestions... anyway.

Once a cave front gets a door built on it, no light enter the cave, even if the door is open.
This is partially mitigated by Building | Wooden | Ceiling & Floor which illuminates the interior.

So my suggestion would be to allow an open door &/ shutter to let light in the cave. Say 5-6 tiles 10-12m
AND
Do not auto illuminate the depths of the cave even with built ceiling&floor.

If no more lighted interiors please add a lamp or candle like item so cave dwellers don't have to always have a lit torch.

One of the tiles at the mouth of the cave is called "surface of the earth". This is a special tile that generates the light. If you build a door or wall over it, it breaks. When I build in caves, I find that tile early on and drop something on it as a reminder to not build there.
