###  bans [wildcard]
###  bans all
   shows you the list of permanent bans stored on the bot, and
   their respective attributes.  here's a sample entry:
      [ 5] *!*lamer@*doofus.com (perm) (redbird: ctcp floods)
   the number (5) can be used to reference the ban if you wish
   to remove it (see '.-ban').  next is the actual hostmask being
   banned.  the "(perm)" means that the ban is "permenent": that
   is, it doesn't automatically expire.  if there is an elapsed time
   showing instead, the time displayed is how long the ban has been
   active.  those kind of bans expire after one hour.  the last part
   of the ban entry is the comment ("ctcp floods") and who put the
   ban there (redbird).  sometimes there will be a "!" or "*" right
   before the number.  a "!" means the ban is in the bot's permban
   list, but is not currently on the channel.  a "*" marks a ban
   which is NOT in the perman list but IS on the channel.

   if you use 'bans <wildcard>' it will list all the bans (active
   or not) that match against your wildcard.  consider it a 'bans
   all' list matched against your wildcard.

   if you use 'bans' it will show you only the bans which are
   currently in action on the channel.  if you use 'bans all' it
   will show you every ban in memory.  (with 'perm-bans' on, these
   are identical.)
