Deobfusion mistake

EntityLivingBase.addRandomArmor should be dropRareDrop. See EntityZombie:

    protected void addRandomArmor()
    {
        switch (this.rand.nextInt(3))
        {
            case 0:
                this.dropItem(Items.iron_ingot, 1);
                break;
            case 1:
                this.dropItem(Items.carrot, 1);
                break;
            case 2:
                this.dropItem(Items.potato, 1);
        }
    }

Also, EntityLiving.func_180481_a is the real addRandomArmor.
