New index page for spells

A lighter spell-index-page.

So I'm working on a new version of the spell page. Mostly to be able to add spells to an active spellbook without a page-reload. But I didn't really like the bloated information on the old version (that some of you really like).
On the new page you are able (at this moment) sort by name or level, search by name or description. Add selected spells to a book or generate a PDF with spell cards.
You will find the page in the navigation, feel free to like or hate it. But keep in mind, that some features might not work properly.
