Introducing the SD60 Freight Train! - v0.30.0

Version 0.30.0 brings something I have wanted to add for quite a while: a freight train and level crossings, in this case the SD60.

There will always be at least one freight train line, maximum two, and freight trains will move along them between 10-40mph.

There are also level crossings so they can block you when trying to escape a tornado!

I have also updated the vehicle impact physics so road signs get knocked out of the ground when you drive into them. I have also fixed fences, solar panels, power lines and most importantly cows - so instead of an initial impact that stops your vehicle, the impact sends the other object flying away.

As always, enjoy! :)
