Completed levels 1-10 for Snow Course, Minor QOL and bug fixes

Made it so that the ball in the customization scene stays the color that you have selected even when leaving and coming back to the customization scene. 

Added holes 7-10 for the snow course

Look out for more holes coming soon, looking to complete this 18 hole course and then work on a competition mode or a highscore board to increase replay-ability.
