[scikit-image] Turning mailing list reply-to-list on by default

Hi all, There is general debate about whether mailing list messages should reply to the list or to the author by default. My view is that replies to list messages should go to the list, and replies only to the author are the exception. This would also be consistent behaviour with the lists of Numba, NumPy, SciPy, and scikit-learn. I intend to update the list settings in a couple of days unless I get some very strenuous opposition to this message. And even then I might do it anyway. =P Just a heads-up! Juan.
