half-assdely made it possible to see spells of over level 1 in spellbook
you can now decrease charge allocation in spell book as well with right click (will only work with t-engine version 48066ca9b84b473156fc6c971200e02e900b6de5 or greater)
fixed targetting of some spells
fixed summoned wolves leveling up giving error
