Hint File Added + Final Solution Password Change

Hello. Quick update. I have added an optional hint file to the documents, which should help a bit if you're stuck. I have also made a slight change to the final solution password (Murder Method is now just one word - the "weapon") to create less room for interpretation. I likely won't be making any further changes (or adding easter eggs) for the foreseeable future due to work on other projects and an extended vacation coming up, but if there are any game-breaking issues, please let me know and I'll try to fix them. 

Thanks!
