Gameplay and more terrain generation

So I've more or less finished the refactoring and I've begun adding some gameplay elements starting with foraging items from the ground and proceeding from there to some basic survival mechanics, crafting and building, after that I'm adding some neutral and hostile npcs with which the player can interact with. I'm also trying out some different terrain types to see which I should use and so on.

Samuli also has modeled some house parts for the game and I'll be adding them once I have programmed building.

PS: I'm still updating the task list at Onwards
