WHO [(player)] or who [(player)]
WHO lists non-dark players that are currently online.
There are two versions of "who". When typed in all caps,
one player is listed per line, when typed with lowercase,
it'll list players in 4 categories:
ACTIVE: last command was less than 3 minutes ago,
AWAKE: last command was 3min-1hr ago,
IDLE: last command was 1hr-1day ago, and
COMATOSE: last command was over a day ago.
If given a player name, it displays only the matching names.
Gods see additional information on the who that normal players don't,
most notibly [[darkplayers]] and hostnames
Wizards can see see certain flags (bot,wiz,god) and last connect times.
There are two player flags that pertain to the formatting of WHO,
REVERSE_WHO and TABULAR_WHO.
