- Raised version number to 0.7.0-b7 for history saving in quetzal files,
   new /config command, i18n and locale fixes, configuration improvements
   and other minor improvements.

 - Added "game_was_restored_and_history_modified" function which will be
   called if a game has been restored and the screen should be redrawn
   by the interface in order to show the restored text history.

 - Added "get_current_locale_name_in_utf8" method to allow "config.c" to
   return current value without extra malloc()ing etc.
 - Implemented "get_default_locale_name" method.

 - Implemented "/config" command.

 - Implemented saving of text history into non-standard quetzal chunk
   named "TxHs".
 - Implemented reading of text history from quetzal files.

 - Renamed "write_chunk_length" to "write_four_byte_number".
 - Made "write_four_byte_number" globally accessible to allow "savegame.c"
   to write z_ucs values into an IFF file.

 - Renamed "store_zucs_in_history" to "store_data_in_history" in order to
   reflect that even 0 bytes may be stored in the given data block.
 - Made "store_data_in_history" globally accessible to allow "savegame.c"
   to write data from restored files into it.

 - Used "strcmp" instead of "strcasecmp" for config variable evaluation to
   avoid locale setting problems.
 - Added evaluation of search path environment variables from filelist.c.
 - Made screen interface refresh screen directly form start if a game is
   restored.

 - Transferred evaluation of environment search path variables into
   "fizmo.c" so they're always evaluated, not only if the filelist is used.

 - Added z-code-root-path variable.
 - Renamed "save-text-history" to "save-text-history-paragraphs" and
   made it a string instead of boolean variable. This is now supposed to
   store the number of paragraphs to be saved in a quetzal-file.
 - Fixed locale and i18n-path configuration options.
 - Made configuration_options[] globally accessible (for "/config" command).

 - Raised version number to "0.7.0_b6" for config.c improvements, minimum
   documentation, many bugs fixes and many other improvements.

 - Made "true_value" and "false_value" referencable from other modules.

 - Fixed output of random generator state for "random-mode" NULL.
 - Added output of story's z-version number in "/info" command.

 - Added i18n_libfizmo_STORY_HAS_Z_VERSION_NUMBER_P0D localization.
 - Fixed german localization output.

 - Moved CVS tags to end of file.

 - Replaced strcasecmps with strcmps since strcasecmp requires correct
   locale setting.

 - Re-worked configuration option system.
 - Renamed "set-tandy-bit" to "set-tandy-flag".
 - Adapted current files to new configuration.

 - Initial documentation stubs.

 - Implemnted "expand_configuration_value" function, which expands
   variables in configuration options. Currently only implemented variable
   is $(HOME) for the current user's home directory.

 - Extended maximum configuration option value to 240 characters.

 - Deactivated FIZMO_UNIQUE_EXIT_CODE. Turns out that return codes
   to the OS are usually ANDed 0xff, which makes the feature quite
   useless.

 - Removed unused variable in "parse_fizmo_config_file".

 - Removed unused i18n_libfizmo_P0D_BYTES_USED_BY_TEXT_HISTORY_METADATA and
   i18n_libfizmo_P0D_BYTES_USED_BY_PARAGRAPH_CACHE translations.

 - Added "locale" option.
 - Replaced many "strcmp"s in parsing with "strcasecmp"s.

 - Made "locale" configuation option standard option handled by "config.c".

 - Added output of texthistory-usage memory in "/info" command.

 - Implemented "get_allocated_text_history_size" function.
 - Removed dead code.

 - Modified "set_current_locale_name" to take char* instead of z_ucs*.
 - Removed dead code.

 - Added variable initializations to avoid compiler warnings.

 - Moved "default_foreground_colour" and "default_background_colour" into
   libfizmo.

 - Implemented "color_name_to_z_colour" function.
 - Moved z_colours from fizmo-ncursesw interface and libcellif into
   libfizmo types.

 - Implemented "foreground-color", "background-color", "enable-color",
   and "disable-color" options.

 - Implemented config options without values.
 - Moved "foreground-color", "background-color", "enable-color" and
   "disable-color" into libfizmo configuration options.

 - Removed unused "factorial" function.

 - Implemented "wordwrap_destroy_wrapper" function.
 - Implemented output_left_margin.

 - Raised beta version number due to libcellif-separation.
