TG: Add Buttons

Buttons are an essential part of games, and they seem to cause problems to beginning game designers. I know they caused me lots of grief and I was so joyful when I was able to get my first button to work successfully. I even remember when it was and the game that I was working on. I don't remember why it was causing me so many problems, but I simply did not understand how to make buttons based on what I saw on the wiki, and I had never had any instruction in person. It was a major breakthrough when I figured it out and it took me a long time before I actually felt comfortable with them. That's why I make sure that my students really understand how to make them and I go over them so many times thoroughly so that they don't suffer like I did. If you need to get from frame to frame without having any other kind of coding, a button is the easiest way to do it. Buttons can be simple to complex and colorful to bland, but they serve an important purpose to games. It would be very difficult to make a game without one, I think.
