Fire in the cube!

• Added Gunpowder Block
• Added Redstoned Gunpowder Block
• Added Sticky Gunpowder Block

Of course explained in the description, but i'll hint it's uses here. Gunpowder blocks can be made with 4 gunpowder and if it's a special type (like redstoned or sticky), then it's special crafting ingrediant and then boom! or not boom yet because it's only been crafted. Igniting it with a flint and steel or fire charge will explode it INSTANTLY and when a gunpowder block is blown, so are the others around (and instantly too!). The redstoned gunpowder block will make it explode when powered and the slimy gunpowder one won't make it affected by gravity.

Have Fun!
