Updates to game file and Itch page

Updated the Score to include a better description of clifi and solarpunk, removed the paragraph about bandits and company towns and such, since those are not actually featured in the game's written contents. Added more solarpunk and clifi reads to the book club section. 

Added more images to the Itch page from the pdf file, also changed the cover image and major game image to have the time more prominent. Made textual changes to the Itch page based on those made in the Score in the game.
