Implements a player attribute system that's currently only used for food
The game displays a food ticker counting down. When it reaches 0, you die. It takes an hour to deplete.
Allows adding player attributes. Right now they all make the player die when it depletes in an hour.
Adjusted the item food editor to accept player attributes in order to modify them. You can add any number of attributes and configure negative numbers as well
Tested that the player can eat an apple and it restores food
Requires #333
