- added some missing changelog entries to the 4.0.5 changelog
 - applied small fix to configure.in from monty (already applied manually
   to configure.in of the 4.0.4 release source files - not relevant for
   normal builds anyway)


Docs/manual.texi:
   - added missing changelog entries
   - added the 4.0.4 release date
configure.in:
   - bumped up version number to 4.0.5-beta, now that the 4.0.4 builds
     are done
   - applied fix from Monty to be able to build shared libraries even
     when the the static NSS libraries are installed. This patch has already
     been applied to the released 4.0.4 sources to work around a local build
     problem, but has not been checked in yet.
