Massive changes.

- Changes how it mitigates damage.
- It now only affects external attacks (punches, mobs, items, guns, etc.)
- Now is PRE armor mitigation! https://i.imgur.com/CXx82J5.png
- Adds variants. Allows mobs to use the new variants, but not the pack itself.
- Adds an extended description and fluff text.
- Adds ability to have both min&max for each variable.

I still need to make them have specialized recharging batteries (especially for the belt unit), but currently the normal recharging batteries are fine.
