Allow Multiple Armor Slots?

[DarthFutuza]

Currently .arm (armor files) expect one of the following responses for the "slot" field:

• "head"
• "neck"
• "torso"
• "robe"
• "legs"
• "gloves"
• "boots"
• "shoulder"
• "implant"

Attempting to do something like ["gloves", "shoulder"] is invalid. However, we may want to expand this as there could be some armors that take up multiple slots. If we were to allow this in the future, then we probably want to store slots in a vector or as toggled bits in an integer. These would need to be checked anytime a player equips/unequips armor, to make sure that the slots are reserved and you can't wear other items in those slots. Inventory/shop menus will also need to be altered so that it shows all the slots the item takes up. It is likely that we probably want to only do this with very specific items such as full body armor that covers up most slots.
