[scikit-learn] Github project management tools

Thanks for your thoughts.
I'm working in a similar mode, though I kind of try to avoid too much 
last-in first-out - I do it too, though,
because I'm trying to keep up with all notifications.
However, there are many older PRs and issues that are important 
bug-fixes and they get lost because of some minor new feature being added.
Your point about faster communication in recent issues is taken, though.

But I feel we should prioritize bug fixes much more - they do need more 
brain power to review, though :-/
