Fireproof Trains

Allows trains, locomotives and cargo/fluid wagons, to drive through fire and not take damage by changing their fire resist to 100%. I had a problem with biters attacking my walls right where my gate was and after my flamethrower turrets killed an entire train load of ore coming in I decided to it was silly that a fire would kill a train with 1 second of exposure as it went through. Fire already does not hurt train tracks at all, so this made sense to me.

It should work with modded train types as well, though I have only tested it with electric trains, and nuke trains in K2
