Added item data, Added handlers to fetch item data and format it, Added starting gear

[BrunoCDev]

• Added item data in json format (folder data/items...)
• Added some handlers/parsers to format this data into something we can actually consume (We can call generateItem() in handlers/item.py to create any item that we have data for).
• Starting gear for each class is being generated using this and applied to the character in lobby.

Will need to make some extra changes if PR#69 is merged first to plug it all together
