Basic Main Menu in place

I've implemented a pretty simple main menu with some buttons on it. None of the buttons are hooked up yet so that'll probably be the next task. The main menu is accessed after the user passes the splash screen. Text/Graphics should be added to these screens. I'll probably add some sort of disclaimer/GNU notice on the splash and the title on the main menu. For the background I want to play a video, this will probably be a video of me playing the game when I get the game/video components implemented.
