Add an Item system

TODO

• Read in items from a JSON format
• Create objects based on item types.

So, for a bit of an elaboration. I think it would be good to have item data stored separate from the code in the JSON format and use the code to read these items in and populate the world based on those items. We can then easily add new items or tweak item stats in without changing the game code.

Example:

'items': [
    'knife': {
        'damage': 4 
        'weight': 5
    },
    'sword': {
        'damage': 8 
        'weight': 10
    }
]

These items and attributes are just placeholders, but the item system should be able to handle that somehow. I think python natively supports reading in JSON objects. If that's not clear, feel free to leave a comment.

How is progress going on this?
