Heavy Potion - Armadillo scute

Hi guys,

It's been a long time since we had a new potion, so I was wondering if maybe a "heavy potion" would be a good idea.

It would be crafted from armadillo scute and would prevent the player from any knockback effect for a certain duration. This would fit with the scute and also give the player a new way to prevent unfortunate deaths (pushed by zombies or creeper explosion) and a nice counter to the Breeze and the wind charges.

Thanks for your great work !
