Sanity Simplified for Convention 1.0.0

I created this file for Gamestorm in Portland in April, but I just realized that it might come in handy for others running Call of Cthulhu for new players (and new Keepers). It's basically just the rules from the corebook simplified into a single sheet for quick reference. I put it up on a display stand in front of my Keeper Screen so that everyone who sat down at the table could see it, especially when they were losing sanity through the convention adventures.
