Added Item Prefabs and Interactable Prefabs

[SB-Lamia]

I added prefabs for the three items and interactable items that you can drag and drop. all it needs is the itemmanager in the scene and the item hud added to the canvas.

you also need to edit the canvas to be scalable (1920x1080) and width/height to be edited.

Should be easy to find some good assets for the items, we can adjust the canvas after as well.
