Add "Thanks!" or "Thank You!" to SpeedChat at the bottom with "Yes", "No", and "OK".

When the chat starts lagging, and you're constantly trying to thank people for Toon-Up or something else, it can be pretty infuriating having to mangle your way around the SpeedChat menu to click the "Thanks!" button. This would also be faster than just typing in regular chat too. It most likely wouldn't take very long to implement either, since chat phrases have been added by the TTR team as well.
