Functional Hyper Training!

There are ways this can be improved (SFX, menu message, insta-recalc stats), but this finishes the Hyper Training functionality.

Talk to James, give him a Bottle Cap, he boosts your DVs to max, and then he deducts a Bottle Cap.

Notable that vanilla vitamins don't recalc stats immediately as well, so maybe the recalc bit isn't necessary.
