Change ordering of memberlist to not try to compare lastActive of 'currentlyActive' users, as lastActive may will be a complete lie as it only gets updated when currentlyActive transitions to false (i think?)
Remove order by online/idle/offline in favour of "currently active, ordered by power and then alphabetic name, followed by last active, followed by offline"
Add commented-out code to track last-spoken-within-a-room ordering.
Fix kludges due to SYJS-28 (depends on JS PR landing)
Still slow when typing due to adding 1000 tiles to the DOM, but it is at least
a lot better than before (which would stutter on ANY change to the member list)
