Updated passwd-file format to allow specifying any key=value fields. Since the value fields may contain ':' characters, this changes the file format a bit. Previously the last two fields were "flags" and "mail". Flags has been empty for last 3 years however, so the new format is used if the flags field contains something. In that case there is no separate mail field, it can instead be specified by adding userdb_mail=<mail> parameter.
