Sort the spells before you print or generate a PDF

I've added the ability to choose how the PDF will sort the spells when it's generated. By default it's the default order..duh! (level, a-z), but you can choose to generate the PDF by the way the tables state. 

It's important that you first sort the spells and after that's done, you can check / mark the spells.
