Bukkit

• Add disarm spell
• Fix armor not dropping on death if the wand inventory is open
• Some wand randomization fixes
• Add duration property (supported by levitate and invincible)
• Fix spawn spell when the actual spawn point is underground.
• Cap enchanting wand levels to 40, and fix the way levels are presented when enchanting. (including w/ bookshelves)
• Add right-click-to-cycle option, for all the wand inventory haters out there (er, everyone but me?)

Issues I've noticed in 1.7.2 so far:
- The lightning spell creates no visual effect
- Enchanting is a little wonky, something to do with swapping out the item for an enchantable one, I think. Seems to work though.
