Refactor Metalmind Selection Code

[leafreynolds]

The code that chooses what Metalmind to tap/store is one of the oldest pieces of code in the project, and likely needs a refactor to improve performance and be more intelligent about what order the metalminds will show in.

• [ ] Improve performance
• [ ] Improve Metalmind selection order (Hotbar, Curios, armor, inventory)
• [ ] Config values for the above to change order

While we are in the area, we should:

• [ ] Fix bug that leaves only a few points left in a metalmind
• [ ] Allow grabbing points from multiple metalminds at once as part of one request (which may fix the above)

Ooh, I never thought to say - I think I found a solution to the bug where a few points were left - all you need to do is tap or store at level one, depending on whether you're filling or storing.

I'm still open to a proper solution, though, especially as this workaround doesn't work for copper.

May be worth taking a look at Hexcasting and media works for reference, Hexcasting has to deal with finding media (amethyst and related) in the inventory, and media works implements a better algorithm for the same
