Rename MyScene To SceneBoard

Rename MyScene to SceneBoard because the new name is more descriptive
of what the scene will be doing instead of a general name. Also, remove the
sample code since it is not going to be used. Add in the background
colour that will be used throughout the game.
Remove Sample Image From The Game

Remove the sample image from the game since it is not going to be used.
Add Game Boy Font To Game

Add in a game boy like font to the game because the design will be a retro look
of a chess video game
