Add '--disable-overlay' cmdline option.

The option will prevent the overlay from attaching to Among Us while
also disabling the workarounds that got the overlay's transparency working.

This for those who have trouble with CrewLink's overlay since the
'hidden' overlay setting within CrewLink doesn't completely
stop the overlay from attaching to Among Us.
