Fixed [0.9.167-PUBLIC#7262] Foxfire/Frostfire Transmutation Bug

[Theron]

1. Have Foxfire and Frostfire in the inventory.
2. Use Foxfire.
3. The Frostfire will become Foxfire.
Does not seem to happen the other way around?

Hopefully fixed for the next release.

This should also fix similar items if they use the same method of being used with other items in the inventory (below them) that are extensions of their object class.
