What's on the menu?

Now we actually have a partially functioning menu in the beginning of the game instead of just a screen displaying some text. I say partially because at the moment no matter what option you select from the menu you will always end up in the same place: the gameplay screen. Also now you can rotate the camera around the player character and look at it from different directions. There is something funny going on with rendering the scene though. Sometimes things that are further away are rendered on top of things that are closer to the camera. I have some ideas in my mind for that, I'll start working on the issue next.
