This is mainly a patch for an issue in 4.7 where wand mana regen rates are about 4x what they should be.
Something exciting has snuck in, though- I'm still working on it. The Magic Hat is Magic's first wearable item- hopefully more of that to come.
- Fix mana regen rate (it's 4x what it should be)
- Allow mana to regen while not holding a wand
- Add Magic Hat item
