IrcAdmin: sleep a configured time before autojoin

this is to let any sort of autosend commands apply before joining
channels. for example, i have my bot set to turn on its hostserv cloak,
which was sometimes happening after channel joins, making its hostname
appear different in various channels. this solves that

as a total aside, this module is becoming really poorly named, i should
probably do something about that
