Issue Description:

Armor energy refill doesn't check energy container type.

What happens:

When the armor needs energy, it drains it from items like 'The Ender' if located in inventory (hotbar is fine).

What you expected to happen:

The armor refill code should check the type of items in your inventory before draining them.

Steps to reproduce:

1. enable the armor refill option in the config file
2. equip powered dark armor
3. put a charged ender sword in your inventory
4. take damage/jump/otherwise use energy
   Your weapon now lost part of its charge.

There's no "energy container type" to check, but dark steel items should not allow energy to be pulled out, so that fixes this, too.

With type I meant checking whether the item extends sword/armor base classes (which should work? correct me if there is no such thing), but what you did seems the better/easier fix.
