Adds mod settings to adjust the various values for train pathfinding penalties. Can allow for increasing or decreasing the likelihood of trains picking certain paths based on stations, red signals, circuit integration, etc.

This can let you tweak your train preferences, or can be useful for testing. Instead of lining up a bunch of stations or locked signals to add tiles to a path you could just change the penalty value for a train going through a station. Though extreme changes may have unintended side effects such as trains from considerably further being prioritized.

WARNING Setting any value to 0 can cause train backlogs basically anywhere, if you want to try it out go ahead, but especially with the Ticking Idle Penalty i HIGHLY recommend not setting it to 0.
