Update Notes for Build 0.1.8

- Fruit trees now produce fruit.
- Most crops and crafted items now display a quality level. There are 7 quality levels beginning with Standard as the lowest. As you increase your crafting and farming skills, your chance of higher quality items increases.
- You can now add Potash to tilled soil. Potash is a fertilizer that increases the chance for higher quality crops.
- Fixed a bug where items on the map displayed in grey when the game was paused.
- Fixed a bug that sometimes displayed the map prematurely when using the world map to travel.
