Feature request: View maps by number of stations

[shannonturner]

This request comes in from email:

I kind of want to see other maps with such a large number of stations, the problem is there aren't very many, and trying browse them by date takes forever for this(though I also use this feature a lot and really appreciate it). I was wondering if it would be possible for you to add a feature where you could sort maps by date by number of stations they have, rather than just by when on the day they were saved.

Would be pretty easy to arrange, since station counts are already stored.
