Additional text editing and CG gallery errors fixed — Chasing the Stars Steam update #654898

I've posted a new build, fixing one of the CG gallery images still not showing up, edited a bit the text, cleaning typos and such, and fixed the achievement for Ending 12. Unfortunately, the "All Ends" achievement refuses to work, so after sending it to some friends with more knowledge of programming and getting only confused frowns, since everything seems to be in order both in my end and on Steam's end, I finally decided to delete that achievement and move on. I'm sorry for the inconvenience and will compensate it adding trading cards in the near future.
