Space Raptor Tutorial 3 Status

I did some work on the next Space Raptor tutorial today. It covers adding in a shield for the player and a power up that gives the player a three way shot. It also adds a frames per second counter so you can gauge how well your game is performing. I'd recommend baselining it on an empty game so you know how hot your machine runs when it is unthrottled and what impact your code changes has on your games.
