- Added set::spamfilter::virus-help-channel-deny. This allows you to block any

normal joins to the virus-help-channel. This way you could prevent users into
  accidental (or tricked) joining of the virus-help-channel and becomming infected.
  This feature is disabled by default. Requested by bleepy (#0001811).
