clientbot: track failed KICKs with /NAMES & a timer

Suggested by @cooper.

This tracking system solves the problem of failed relay kicks causing channel desyncs, because what's seen as a successful KICK when PyLink is linked as a service might not forward
successfully on clientbot network. This can be caused due to the clientbot not being opped, the target being immune or having higher access than the clientbot, etc. When a NAMES reply
(delayed in this case) is received for any channel where an initial /WHO has already been received, a JOIN hook will be sent for any users on the kick queue to rejoin them on the relay.
