Inventory Update

Items can be (un)equipped. Stat changes are shown, and items are removed
from the inventory list in the GUI when equipped. An error is sometimes
generated when equipping an item - it has something to do with the list
of items being displayed.
Merging Update
Fixed Camera Issue

Camera issue was with how it was tagged. I changed the tag and updated
the player prefab. No visual changes but the errors should be gone.
