feat(noitu): make /noitu the group game and add /noitutop

/noitu now posts the group play card that /noitupvp used to, and the solo
game against the bot moves to /noitubot. In a private chat /noitu points
the user to a group, or to /noitubot.

/noitutop ranks a group's players across all of its cards by wins, best
game and games played.

A one-time startup migration moves /stats history to the new names in
order: noitu to noitubot first, then noitupvp to noitu.
