Update 1.1 Uploaded

I made some changes to the document.  I changed the term monster to threat as there can be many types of things that hunters get involved in from curses, artifact/book retrieval, phenomena, haunts, etc.  I changed The Enigmatic Heirloom mystery so that the threat is the actual "heirloom" with a possible second threat with the demon. I also made a couple of minor cosmetic changes as well.
