Verbesserte große Garage [1.36.x]

I made some fixes and improvements to the big company garages (those found in cities in Scandinavia, Vive la France, Italia, Beyond Baltic Sea and Road to the Black Sea DLC).
Besides the bug fixes you can see on attached screenshots I also added some workers and random AI trucks so your garages should feel more alive.
Additionaly I made all garage doors openable so you can drive around your garage if you like so.
