Style improvements and cost calculation alternative

This commit adds a lot of missing comments, and fixes a lot of bad formatting. Some spelling errors have also been fixed.
Warning: This commit changes the name of some config values. Existing configurations will be broken!
This commit also adds a natural cost option, which defaults to true. With natural cost turned on, the cost of repairing an item will increase with each damage the item has taken, rather than the cost decreasing for every damage taken.
