Support multiple connect commands.

Support arrays or similar in the configuration file (for nick(s), connectcommand(s), etc.)

All the TODOs sprinkled throughout the code!

Use connecting/disconnecting IPs instead of fd numbers in NOTICEs and both in debug.

Option to include date in replay log replay.

(I think) replay log can cause non-existent user to appear in channel (e.g. ~19:00 on 12/08/2019 for me)

Do server operator messages and commands work?

Add BLABOUNCER HELP as a valid command to avoid the unrecognised command error.

(I vaguely recall) some unwanted stuff (channel ban info?) was relayed to another client upon a client connecting.

PM replay chat in a channel (or perhaps a random channel?) e.g. replay on 06/09/2019 at 17:05 from 13:49 in #insomnia - maybe a client thing.
