Explosive Snowball

This plugin adds an item called "Explosive Snowball" to Minecraft. The item can be crafted using snowballs and gunpowder and can be used just like a normal snowball, but upon hitting a block or entity, it will explode and cause damage to nearby entities. The recipe for crafting the explosive snowball is also included in the plugin. Additionally, the plugin has code to prevent players from renaming a normal snowball to "Explosive Snowball" using an anvil, to ensure that only the intended item can be used.
