Documentation:
Track the time of the last PRIVMSG for each (server,nick) pair.

This is implemented as a hash of hashes, where the outer key is
the canonicalized server name (as returned by
`erc-canonicalize-server-name') and the outer value is a hash
table mapping nicks (as returned by `erc-lurker-maybe-trim') to
the times of their most recently received PRIVMSG on any channel
on the given server.
