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!

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?

(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.
