Properties should not be created in the block class

[LukeGi]

It is not best practice to create properties in the block class. You should instead pass properties to the constructor when creating the block.
By doing this you allow for other mods to potentially extend the block, may not be applicable here but it is still not good to demonstrate bad practices.

	super(Properties.create(Material.IRON)
	.sound(SoundType.METAL)
	.hardnessAndResistance(2.0f)
	.lightValue(14)

The same is true for Items.

Lines 18 to 20 in 513b179

	super(new Item.Properties()
	.maxStackSize(1)
	.group(ModSetup.ITEM_GROUP));
