Adds warnings to train tracks that are about to be occupied by a deadly train! Does not work on manually driven trains and will not show you enemy trains.
Added a configuration to disable warnings while riding a train.
Modified dot size setting to allow non-integer values (so values of 0.1, 0.75, 12.5 are valid)
Updated for 0.18.
Added settings per player to disable the warnings, to increase the length of the warning path, and to increase the size of the dots.
Now hides the indicators from enemy trains-- FUN FACT: In vanilla factorio you can connect your wagon to an enemy train wagon and basically take it over. Each carriage maintains its force, so unfortunately you can't just steal their stuff. Also, you can just add train signals to enemy tracks and close them with a circuit condition to stop their train traffic.
Slight code cleanup (hopfully desyncs are prevented in multiplayer)
