- Windows: When trying to load a module (DLL) windows can give us the

  mysterious error 'The specified module could not be found' even though the
  file exists. This usually means that it depends on another DLL, but
  apparently Microsoft decided not to mention that in the error message.
  We now append some small text when such an error happens, saying that it
  could be because of a missing dependency. Reported by Phil.

 - Added set::options::allow-insane-bans which makes it possible to set
   really broad bans such as *@*.xx. Needless to say this can be very
   dangerous. Reported and patch provided by Stealth (#0003963).
