Added lights effects for all the cabooses

Hey, welcome back!

The new Train Mod system is out, it was about time to convert the mod to it.

But, that alone wasn't good enough, so I've decidd to make some changes to the models and also add some new!

These are the changes made to the old models:

- Added some texture to the Bay Window, now it doesn't look so flat;

- Added some details underneath the transfer caboose, It was too simple for my taste;
&
- Added some fine details to the wheels and couplers.


The new models included in this update are:

- A modern looking Bay Window;

- Another Extended View, but this one is a little shorter;
&
- Centered Cupola Caboose.


This update might break some textures, but I believe it's an easy fix. I've maintained the same UVs, the only difference is that now the wheels, couplers and lights have their own textures.

For unknown reasons, I don't know why the wheel models don't flip. I'll try to fix it as soon as possible.

Anyway, hopeyou all enjoy it!

If you have any problems, please, let me know!

- Complete rework of the models and UV maps, so now it has much more details.

- The Offset and Extended View Cabooses have been rescaled, now they should be the right size.

- Added lights with a unlit map, so they're able to glow in the dark.

*WARNING*

This update WILL break any livery you have installed/created, IF they're not updated yet.
