Receiving mentorhelp responses should play a sound

[Carbadox]

Definetely. There's been a noticeable amount of MentorHelps that haven't been getting replies back from players, which I'm guessing is probably coming from the fact that you can play most of the game now without having to look at the chat box once. Ideally, I think the prompt for recieveing an answer from mentorhelps should also be more clear. Now that dark mode for the chatbox is the default option, purple text on a grey background blends in too much.
