ETS2 - Volvo FH 2009 Correct Roofs & Spoilers V1.0 (1.37.x)

The low & medium cabs in-game look nothing like the real thing, and this is my attempt at fixing that.
I wanted this to be a quick project, so only the roof is replaced, and the level of detail is consistent with the rest of the truck. This means that the term "correct" is used a bit loosely here. 

Changelog;
- Standard cab - new roof, added a spoiler.
- Globetrotter - new roof, added a spoiler.
- Globetrotter XL - the medium cab is now the XL. Otherwise unedited.
- adjusted exterior seat position. From 1st hand experience, you can't position your seat like that in a Volvo, and then sit in it.

There are 3 banner/sticker things for the medium cab.
