Simple Transitions Added

Just implemented some simple transitions and a continue screen.

The continue screen will be used for the stats/star system that I plan to implement later this week.

I will have to set the star rating manually for now. Something like Perfect = 3 stars, Perfect to -5 Equals 2 stars, and -5 to -10 equals 1 star. Below -10 is no stars. So essentially there are four states deepening on the amount of moves used to create the level. If I just set the variable perfect for each level, the code can easily do the rest of the calculations.
