Chainmail - Craftable Chainmail Armor

Simply added bStats Plugin Metrics to the plugin.

This update fixes the shaped crafting, you can now craft the helmet and boots like other helmets and boots. The chestplate and leggings recipes have not been changed. This update also makes chains a bit cheaper to make, by giving 3 chains instead of 1 when crafted. This is due to chainmail having the same armor rating as gold, yet having the same durability as iron. This made iron armor more favorable, as it cost less to make, making chainmail obsolete anyway. This way, chainmail is considerably cheaper, and allows for an individual to craft chainmail armor before having to make iron armor.
