New Settings and Color!

Added Teal as a color! I want to add more colors, but I’ve used most of the rainbow now so don’t know how many more will be coming. I also added the ability to change your leaderboard display name, and the ability to replay the tutorial. These can both be found in the settings page. Getting the leaderboard display name to change was actually more challenging than I thought it would be due to a bug in the Godot CheddaBoard SDK that I was using, but the updated Github had a version that worked! One thing to note about changing the display name: The change will not appear on the leaderboard until the next time you submit a score, or in other words till the next day.
