[Magiclysm] Artificer attunement passively recharges batteries in inventory

[Standing-Storm]

Summary

Mods "[Magiclysm] Artificer attunement passively recharges batteries in inventory"

Purpose of change

This was on the Magiclysm design docs but hadn't been implemented yet.

Describe the solution

Implement an EoC that runs when you have the Artificer attunement. Every minute, it adds power to all batteries in inventory equal to the total levels in your Artificer attunement spells.

It only works on loose batteries because the docs said "batteries," so I went with the simpler implementation.

Describe alternatives you've considered

Testing

It works.
