Implemented magic system

I set up the magic system for the server
ill just sum it up very briefly here:

you start out with no spells at all. you have to LEARN spells from tomes that can teach you spells. Tomes are special books/bookshelves. Once you learn the spell you can cast it without the tome. type /cast [spellname] to cast it. or you can use a wand stick/goldsword/goldboot. spells cost a selected amount of redstone to cast. if you didn't learn the spell you can cast it with a scroll. scrolls can be bought in selected places and are used to cast spells without the need for redstone or learning it. scrolls expire after five casts. scrolls are paper and arnt stackable btw.
