v 0.8.3 - Oracles!

Mostly squashed some typos, but also added some nifty (and, hopefully, useful!) oracles/roll tables to the back of the book to aid in hunt creation and running the game. 

Changelog:

• Addition of an appendix containing oracles for things like clue inspiration, complications, NPC details, etc.
• Changed "neutralize" to "contain" in showdown questions and hunt creation guidelines
• A lot of typo fixes and wording clarifications -- where did all these typos come from??
• Added quick description of actions to the player reference sheet
• Added a hunt worksheet for players to track clues and other important information during hunts
• Updates to the index
