Added a Tutorial at the start of the game

I'm happy to announce that I finally got a little tutorial added at the start of a new game. There you will learn the basic moves of our protagonist, Novak. You'll soon know that he is capable of more than just swinging his sword. You will also learn how to use and buy items to aid you in your journey. Just take your time get familiar with the controls you set up in the configuration in the main menu and try to make use of the new knowledge you learned from the tutorial. ^^
