GOG 2nd Class Helper από Daniel

Adds information about whether or not a game is on the list of Games that treat GOG customers as 2nd Class at https://docs.google.com/spreadsheets/d/1zjwUN1mtJdCkgtTDRB2IoFp7PP41fraY-oFNY00fEkI/

Note: Only works on the standard versions of games, ie. not on "Complete" editions, etc.
