Added basic inventory system. Now you have tent that you can build, an axe to chop down trees to get woods and destroy your tent. And woods can be now used to make fire. "e", "f" to change items in inventory and "x" to use.
Added villagers and a cute little dog. Villagers have very basic AI. They only go randomly. But the dog is different. Your dog will feel safe when he's near you, and when he feels safe, he will wander around forgetting you. When your dog is lost he will feel unsafe and bark. So when that happens or if you just want your dog, try whistling (press "c"). Press "x" to chop down tree.
