Turn Radio On When Player Loads In

[Niko]

I loaded into a few trains today that were already enroute. Immediately, I was being docked 100 pts per second for driving with the radio turned off. Twice, I couldn't even figure out how to turn it on. (Maybe the buttons weren't working? Because I think I found the radio in the cab, and tried clicking every button I could see on it. That may be a separate issue. Alternatively, if it was user error, tutorials could help.) Only in the EU07 was I able to turn on the radio. In general, this was a very frustrating experience.

If the train is already enroute, or at least turned on, when the player loads in, it would follow that the AI for which the player is taking over would've had the radio on. Thus, it would make sense for the radio to be turned on when the player loads in. This would also be a less jarring experience for the player, instead of being thrown into an already moving locomotive and immediately docked points for something they had no control over.

I added this today to main branch, so it should be in the next patch. If the bot is in charge and radio is disabled, it should also no longer trigger penalties.
