Suggestion: have an option to hide solutions for old versions of the exercise in community solutions

[Enomai]

I find when sorting community solutions by 'Most stars first' or 'Most comments first', many of the top solutions are often for older versions of the exercises. While there's usually still something to be learned from looking at them, many of these submissions are more than 5 years old and have little relevance to the exercise in its current form. It would be nice if we were able to exclude these solutions from the list, in order to more easily browse the best answers for the current version of the exercise to compare to our own.

I like that!
