- moved "/obj/ info slot definition|..." to "/obj/ info object slot definition|..." for consistency - provided "parametersyntax()" for "object mixin" and "object filter"
- bumped version number to 2.0b5 - tested with NaviServer and OpenACS (new version of nx needs as well a newest NaviServer, since ns_cache implementation needs to be objectified; newest NaviServer version works as well with older nx)
