More password paranoia: Allow omitting the identify/register password as
well (and enter it using /OPER instead).

This is a gross hack and indeed still not solid: In irssi one can still
use /RAWLOG SAVE to find the OPER line sent to BitlBee (and of course not
everyone uses SSL to talk to remote BitlBee servers). This only works
within 10-30 minutes after entering the password though.
