Updated main.rs adding a fix for multithreading

I added a fix for multithreading {I am actively in pain send help aaaaaaaaaaaa}
Once activated autoclicker now doesn't kill the program instead making a background thread that adds X amount to the current players score.
The thread Is currently not killed upon program close and you should probably not run It, since It leaves a dangling thread.
Cheers
