Change display text format etc.

We've changed the display text format, and it now looks clearer in most scenes.

We've also added a border to the text on the in-game phone screen, which we think makes it easier to read regardless of the animation color of our custom CPU.

Also, due to a change in Twitch's specifications, the previous method was no longer able to obtain chat content, and as a result viewers were no longer able to choose where to place their stones. As a result, we've changed the procedures to reflect the change in specifications and have explained them in the instructions.
