Suggestion implimentation patch!
*Span classes the whole update
*Spellbooks no longer vanish after being used, instead used spellbooks now have various bad effects should they be attempted to learned from again (the original reader won't acidentally fall to this, as they will just say "I've already read this"). Leave em out as traps for people or properly dispose of your trash! Or...
*The charge spell can now attempt to recharge one use spellbooks so someone else can learn the spell. This only has a 20% success rate and will destroy the book should it fail (even if the book was actually unused). You can't attempt this on the wizard's spellbook
*The "staff of nothing" (functional) placeholder now uses the generic staff sprites
*Spellbooks can now be placed in bookshelves just like normal books
*The teleport spell won't yank anchored things anymore, but as a consolation it will warp the entire contents of a tile should it be targeted. The code has been tweeked so this shouldn't effect the server too bad even if large numbers of items are warped to unique locations this way
