KustomShop XP

Now it works.
Some things I noticed:

- When I buy some items and sell them back to the trader the amount of resold items will be added to the wrong items. (For example when I buy the 2 bronze
swords and 2 iron swords and sell them back he will get 4 iron shields)

- When I sell any other item, for example dispel herbs the amount of sold dispel herbs will be added to the amount of potions he is selling
- When I leave and re-enter the shop all items reset.
