 - 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

+- 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.
