Small fixes — Three Weeks On The Atlantic Steam update #463734

Fixes: - Fixed some grammar errors. - Added a check mark on the NSFW filter to check which one is currently being active. - Added persistent to the NSFW filter so it saves. - Fixed the "A Good Movie" achievement not being displayed for some users. One thing to take into account, to get the achievement you will need to replay any ending so it can trigger again. The NSFW filter will save from now on, so if you save your game with it being on and then load that save, it will stay on. If you load a save that had it off, it will set itself to off.
