Add tool durability

[Unarelith]

Tools should have a value storing the amount of times they can be used before breaking.

Also, a progress bar should be displayed on the item to let the players know when their tool will break.

I can work on this if any of the main contributors help me navigate the codebase.

@fedqx I can help you through it if you come on either IRC or the Discord server. :)
