Some irc channels can only be joined by identified users, but since 
identification may not happen until some time after a server connection
is established, autojoin currently happens too early for these channels.

This patch allows the autojoin timing to be selected:

  - on connect (as currently)
  - after successful ident

If after-ident is chosen, there is also a customiseable timeout which
kicks in and starts autojoin anyway if an ident isn't received in the
alloted time.
