Previous/next custom map links

[UpperKEES]

I think it would be nice to have a link to the previous and next map on the page of every custom map.

When you're looking at the scores it would take you to the score table of the previous/next map and the same goes for comments.

Not only would this make it easier to download them, but it would simplify leaving comments / rating maps after playing them.

I know there's a (convenient) online button in the game, but when I just finished a map, I'd like to know what my goal is for the next one.

Edit: I didn't think about the filters when writing the above. Of course it would be nice when the links are applied to the previous/next map within the filtered set, but I have no clue whether this will complicate thing a lot.
