Minor Update - Art, Quirks, Wording

I’ve updated a few things:

• Redrawn the art for the first and last pages.
• Added 10 more Witch Quirks, so it’s now a nice d20 list.
• Gone through and touched up some awkward wording and typos.

Unless the math for brewing potions turns out to be completely broken, I’m going to consider this project complete. If you use any part of it in play I’d love to hear about your experience!
