Fixed an issue with marking the progress of Steam Workshop puzzles when there is no standard solution information contained within the puzzle's .SGF file.
Added a conversion process for Steam Workshop puzzles that are using the .SGF file's move comment field to designate the move as "Correct". The comment will be converted to the standard puzzle solution information. This improves puzzle completion tracking and also allows the "Show Correct Move" button to be used for these puzzles, which previously wasn't available.
