Fixed a bug where some rewards join in the same slot if the icon is the same.
Added rewards with normal items. You can create them in the reward creation gui, doing middle-click in new reward item.
You can add/remove item to this reward type, doing middle-click in the specified reward, and a new gui it will open. Here you can add items just by clicking them on your own inventory. Tutorial in the video
If your inventory is full when you receive the items from the reward, these will appear at your feet.
If you log out while the items are being given, they will appear around the machine where you opened the cubelet.
