Adds a search box to the top of the spellbook which filters the spells by name.
Also reorders spells with unbound first, alphabetically left to right instead of top to bottom.
Please be aware that this could potentially break the spellbook, so use at your own risk. It shouldn't, but it might.
0.3 - Fixed it so you can use special characters in the search box without it breaking. Also puts "see trainer" spells first now.
0.2 - Completely rewrote the addon because the previous version prevented you from casting directly out of the spellbook.
