Well, here's a demo of the item system. However, if you only pick 3 items,
some combinations will not work. I haven't added the scrolling loop and quantity
for every item in this one. Tell me if there are any other bugs I should work on.
Also, since I haven't modified the charasets, you should check the events
to see how the pictures should look.
Or a better way of inputting the events. If you've fixed the 3 item bug,
tell me how or upload the file please.
