Add a command to get next challenge.

[l-bujakowski]

It's not an issue really, just a feature request.

It would be wonderful to have a command that would get next challenge like:

vimgolf next

Challenges could be sorted by added date for this. Also challenges, that user played and achieved highest score could be skipped.

So for example:

I do vimgolf next - oldest challenge is opened. I may play and gain scores. Let's say the best score someone gained on that challenge is 16. My today best is 32. So there is still room for imporevement. Tommorow I come back and vimgolfnext returns same challenge - until I will reach score of 16, or someone would delete this challenge. Then the command would get another challenge, a bit newer. And so on... just a way to cycle through them.

I was about to suggest the same. Happy to open or collaborate on a PR for this feature.
