UI update!

So when finishing the game for the deadline i was given, i made the menus in a rush before building the game. However, I was still unsatisfied with how the buttons looked (i had kept the basic button sprite from unity). So this morning, I made new sprites for the buttons and they look much better :)

I also added a simple if condition in the code so that the 2048 grid appears when you press the big red button for the first time!
