InventoryDialog Modifications
Inventory Modifications

Added floor to the inventory dialog.
Made inventory dialog bigger.
Added behavior to prevent going over the backpack limit by equipping a
two handed item when two one handed items were equipped and backpack was
full. Not, the overflow goes on the floor.
Can equip from the floor in inventory dialog
Also - Tab > Space conversion in character.py and inventoryDialog.py
(hence the huge line count)
