January 2022 version

I fixed a couple of stuff for "October Rust". Changes include:

• "Cheat Sheet" had been completely redone. Not only made in Affinity (not like previous Scribus abysmal product, looking like MS Paint), but also with added character creation handout in second page.
• "Character Sheet" had been redone and shortened to a half of a page. You can download two pieces of character sheet in one page!
• Minor fixes for the rulebook.
