AI carriage lighting

[DazT]

When driving around in an EP07/08 when it's starting to get dark I flick the 'train heat' switch to ensure my passengers are not sitting in the dark, my suggestion is for all AI passenger trains (not empty stock ones) to switch on their internal carriage lights also, say an hour before sunset and leave them on until an hour after sunrise.

I notice the EP07/08 already does auto-adjust the headlight dimming brightness already when in bot mode, so this is a little add-on so that when you're passing other passenger trains their carriages are not in darkness as you pass them.
