Functioning UI

After I had followed the tutorial and completed the base mechanics and game idea, I added in some functioning UI elements so I could calculate a score, restart and add power ups. I also did this now to speed up production time so that the game could go into beta testing earlier.

I created a Game Manager script that controls the functions for restarting and saving the player score. I added comments in the code so I know what I have written and where I could add future mechanics.
