Catch a NAMES reply and record each person as having been seen.
When requesting NAMES on a channel, or when joining one, the server will send
a big list of every participant in it, in a big string of nicknames separated by spaces.
This is done automatically when you join a channel. Nicknames are prefixed
with mode signs if they are operators, voiced or similar, so we'll need to
strip that away.
More concretely, it uses a splitter to iterate each
name and call updateUser to update (or create) their entry in the
seenUsers associative array.
