Great Asset Update Part 1

The old tileset needed to be redone, so I redid them. The mud tiles now slow the player. Stone and bone piles were added. Nothing can walk through the stone, the monsters won't path through the bones. In the next part, the monsters will have new assets in the same style as the goblin merchant. There will be more rooms in the next update, the rooms repeat too much with the current amount. There are new items, which will be the ones actually in the area, as opposed to the ones from the shady merchant from the previous version, although there will probably be a few more. The shady merchant will be on a different level eventually. I also plan on adding more feedback for when you pick up an item and when you take damage. Music will probably change eventually, but not in the next update.
